I found that Mysql 8 don't like table names without `` in requests. So i make changes in function table_by_key in functions.inc.php and in upgrade.php . Now it works. FreeBSD 11.1 Apache/2.4.29 (FreeBSD) PHP/7.1.11 Mysql 8
The improvements are:
- Die with an explicit message when a user is trying to reset his lost password and the option is disabled in config
- Redirect user to main page after password change using relative URL
- Don't leak info whether user exists or has recovery info defined
- Throttle password reset requests to prevent brute force attacks
- Show phone/alt email fields in mailbox/admin edit form only when the password reset option is enabled
- Make database upgrade code compatible with other databases types
- Use the existing password generator to generate OTP. It is now stored in database, unique to each user, valid only for 1 hour and can only by used once.
Unicode support is a much bigger can of worms (see the discussion in #47),
and having just a little part of unicode support in is a bad idea.
You can of course use the xn--whatever notation for unicode domains ;-)
Dovecot password hashes include a {SCHEME} prefix, so it's possible to
switch the scheme while still accepting passwords hashed using the
previous dovecot:* scheme.
This patch adds the code needed to find out the used hashing scheme
from the hash and ensures it gets used to validate the password.

- add check_db_version() to functions.inc.php
- add $min_db_version (needs to be updated at least before the release)
- call check_db_version in login.php, users/login.php and CLI - they'll
error out if the database layout is outdated
- change setup.php to use check_db_version()

- gen_show_status(): escape mail addresses in query.
Fixes https://sourceforge.net/p/postfixadmin/bugs/356/
(mostly - the edit/delete/... links in list-virtual are double-escaped)
In theory this could allow SQL injection, in practise the mail address
regex limits this issue to a DOS (creating a mail address with ' caused
an invalid query that broke list-virtual)

Measure time needed for the nameserver queries, and error_log a warning
if the queries need more than 2 seconds in total.
Inspired by a question from t-ask on IRC, who suffered from a slow
nameserver and had some "fun" to debug it ;-)

- initStruct(): replace (wrong) 'editable' with '_can_edit' and '_can_delete'
- read_from_db_postprocess(): disable _can_edit and _can_delete for
default aliases if special_alias_control is off and not superadmin
list.tpl:
- use $item._can_edit instead of $check_alias_owner
list-virtual.php:
- drop $check_alias_owner variable and check_alias_owner() call
(replaced by the code added in AliasHandler)
- drop unused $sql_domain
functions.inc.php:
- delete no longer used check_alias_owner() function

- build_select_query(): add support for $search['_'] (searching if one
of the $this->searchfields contains the search text)
- getList(): make sure '_' is kept in the search parameters
functions.inc.php:
- db_where_clause(): slightly relax checks - if $condition is empty,
only error out if $additional_raw_where is also empty
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1772 a1433add-5e2c-0410-b055-b7f2511e0802
- better formatting in db_quota_text() and db_quota_percent() results
(for example, infinity sign instead of / 0 for unlimited)
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1744 a1433add-5e2c-0410-b055-b7f2511e0802
- read_from_db(), getList():
- add $searchmode parameter (_before_ $limit and $offset!) to be able to
use query different query modes, not only "="
- add a warning that $condition will be changed to array only in the future
- getList(): filter $condition for fields that are available to the user
to avoid information leaks by using search parameters
(filter is only applied if $condition is an array!)
functions.inc.php:
- db_where_clause():
- add $additional_raw_where parameter for additional query parameters
- add $searchmode parameter to be able to use query different
query modes, not only "=" (see $allowed_operators)
- check for allowed operators in $searchmode
- split query into WHERE and HAVING (if a parameter has
$struct[select] set, HAVING is used)
list-virtual.php:
- adopt getList() call to the new syntax
AliasHandler:
- adopt getList() definition and call to the new syntax
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1731 a1433add-5e2c-0410-b055-b7f2511e0802
- pacol():
- add $linkto parameter (if list mode should link to something)
- replace $not_in_db with $multiopt - the remaining parameters can
now be specified as associated array (backwards-compatible)
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1719 a1433add-5e2c-0410-b055-b7f2511e0802

- db_query(): do not print out the failed query, error_log() it instead
to avoid information leaks.
- update SF forum URL

- new function db_pgsql() to replace lots of
"if ($CONF[database_type] == 'pgsql')) checks
- delete unused function boolconf()
several files:
- use db_pgsql() instead of checking $CONF[database_type]

- move mailbox_postdeletion() to MailboxHandler
- move domain_postcreation() and domain_postdeletion() to
DomainHandler
- adopt those functions for usage inside the *Handler (replace
print with $this->errormsg etc.)

found out that the 'Config' class is too static - it shares its static
data with the 'Lang' child class.
This caused a conflict because we have $CONF[transport] and
$PALANG[transport], and Config::read('transport') returned the $PALANG
text.
To fix this, all texts are now stored as $CONF[__LANG].
I also dropped the 'Lang' class.
model/Config.php:
- mark the 'Config' class as final to ensure we don't trap into the
"too static" problem again.
- bool(): display and log an error message if a $CONF option does not
contain YES or NO (that would have uncovered this bug much earlier)
- add lang() and lang_f() wrapper functions to get $PALANG texts
- remove unused $__cache and $__objects
model/Lang.php:
- deleted
common.php:
- store $PALANG as $CONF[__LANG]
lots of files:
- replace Lang::read() and Lang::read_f() calls with Config::lang()
and Config::lang_f()

- getList: change return value to be always true (even if the database
result is an empty array), and die() if the database result is not an
array.
This avoids some if blocks in various files to implement a fallback
to array() on empty results.
functions.inc.php:
- list_admins(): simplify after the *Handler->getList() change
- get_domain_properties(): change a forgotten $handler->return to
$handler->result() (follow-up for r1534)
list-domain, list-virtual.php:
- simplify after the *Handler->getList() change

- pacrypt(), dovecot:* method:
- allow "." in dovecot method (to allow a suffix like ".b64")
- blacklist SCRAM-SHA-1 (needs -u)
- check against list of non-salted methods to be backward compatible
with dovecot < 2.1 again
Thanks to Szilagyi Jozsef <szjozsef AT yahoo DOT com> for providing
the list of non-salted methods etc.
functions.inc.php, scripts/postfixadmin-cli.php:
- drop unused global variables $table_admin and $table_alias_domain

implements it, let's declare it as unsupported and error out
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1525 a1433add-5e2c-0410-b055-b7f2511e0802
- pacrypt(): some small changes after Szilagyi Jozsef's patch:
- comment out unused $crypt_method
- change $dovecotpw default to "doveadm pw" (unrelated to the patch)
- set $dovepasstest to "-t $pw_db" instead of having two similar
command lines, and also shellescapearg() $pw_db
- use "if (empty($dovepasstest))" instead of "if (empty($pw_db))"
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1524 a1433add-5e2c-0410-b055-b7f2511e0802
doveadmin pw now has an option "-t $hash" which allows to verify
salted passwords (added in dovecot 2.1 AFAIK)
Also, the {METHOD} part is no longer removed.
Patch by Szilagyi Jozsef <szjozsef [at] yahoo.com> - thanks!
(The schemes which requires also the username -u option is still not supported)

- check_quota ()
- allowed_quota()
- mailbox_postcreation()
- mailbox_postedit()
- create_mailbox_subfolders()
The code was moved without any changes, except
- added leading whitespace
- removed "TODO: move to MailboxHandler" ;-)
MailboxHandler:
- change function calls for moved functions

check_quota()
mailbox_postcreation()
mailbox_postedit()
create_mailbox_subfolders()
- use Config::read() / Config::bool() instead of $CONF
- update comment header
- some minor changes to make the code better readable

boolconf() will stay for backwards compability, but new code
should use Config::bool()

- check_domain(), check_email():
use Lang::read and Config::read instead of global variables
(global variables, at least $PALANG, don't seem to work with CLI)
- boolconf():
- use Config::read instead of global $CONF
- drop isset() check - doesn't make sense when using Config::read
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1452 a1433add-5e2c-0410-b055-b7f2511e0802
- check_domain(), check_email(): instead of calling flash_error(),
return string with error message - or empty string if everything is ok
model/AdminHandler.php, model/AliasHandler.php,
model/DomainHandler.php, model/MailboxHandler.php,
sendmail.php, users/edit-alias.php:
- adopt to changed check_domain() and check_email() return value
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1451 a1433add-5e2c-0410-b055-b7f2511e0802
- allowed_quota: if $CONF[quota] == NO, just return 0 (unlimited)
list-virtual.php:
- only eval_size($limit['maxquota']) if $CONF[quota] == YES
($limit['maxquota'] is not set if $CONF[quota] == NO)
Both issues (which caused PHP warnings) were found by TigerP on IRC

configs/menu.conf:
- change url_create_mailbox to edit.php?table=mailbox
templates/list-virtual.tpl:
- replace hardcoded create-mailbox.php with {#url_create_mailbox#}
functions.inc.php:
- delete functions that are now part of MailboxHandler:
- check_mailbox()
- multiply_quota()
- add some TODO notes
config.inc.php:
- rewrite a comment that referenced create-mailbox.php
create-mailbox.php:
- delete - no longer needed

- create_page_browser(): revert r1387 and...
- db_query(): ...replace it with the correct fix ;-) (avoid mysqli
reconnects)
The problem was that db_query() used is_resource() to check if we
already have a database connection, but a mysqli connection is an
object, not a resource.
This resulted in a new database connection for each query. Therefore
mysqli "forgot" the value of SET @row before executing the following
SELECT query (which used a new mysqli connection).
The fix is to also check with is_object() to avoid mysqli reconnects.

- create_page_browser(): include MOD(idx.row, $page_size) in outer SELECT.
This is needed on some MySQL setups which otherwise return an empty set.
Thanks to f-dens_ on IRC for helping to debug it.

- change list_admins() to use AdminHandler (code from list-admin.php)
Note: this changes the return value format to include all details,
not only the usernames. Use array_keys(list_admins()) if you need
the previous return format.
list-admin.php:
- replace code with a list_admins() call
list-domain.php:
- adopt to new list_admins() return value

- _flash_string(): also accept an array of messages, not only a string
- comment updates for _flash_info() and flash_error() to reflect this change

- PHP around 5.3.8 includes hex2bin as native function - http://php.net/hex2bin
therefore we have to wrap our function (which fortunately gives the same
results) with function_exists().

- deleted, obsoleted by edit.php?table=alias
functions.inc.php:
- drop function check_alias() - it was only used by create-alias.php
(AliasHandler has a similar function create_allowed(), which is a
copy of check_alias() with superfluous {...} removed)
configs/menu.conf
- replace create-alias.php with edit.php?table=alias
- append "?" to url_create_mailbox to avoid temporary change in menu.tpl
(create-mailbox is the only one which still needs ? instead of &)
templates/list-virtual.tpl:
- use {#url_create_alias#} instead of hardcoded create-alias.php
templates/menu.tpl:
- $url_domain: url-escape domain, use & instead of ?

- add rewritten function create_admin() (now using AdminHandler,
which means 25 instead of 80 lines)
- various follow-up changes to match the rewritten function create_admin()
functions.inc.php:
- delete function create_admin() - setup.php was the last file calling it
- honor POSTFIXADMIN_SETUP in authentification_get_username() to avoid
a redirect to login.php after creating an admin with setup.php and to
get "SETUP.PHP" for db_log()
model/AdminHandler.php:
- add TODO: implement generate_password
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1301 a1433add-5e2c-0410-b055-b7f2511e0802
- allow log actions create_admin and edit_admin
- add edit_admin_state and delete_admin as comment/reminder that they
should also be logged
*.lang:
- add text for the new "create admin" and "edit admin" log actions
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1298 a1433add-5e2c-0410-b055-b7f2511e0802
- use AdminHandler
- move displaying the superadmin flag to the template
templates/adminlistadmin.tpl:
- update to the fieldnames provided by AdminHandler (name->username)
- move displaying the superadmin flag to the template
functions.inc.php:
- delete function get_admin_properties() (was only used by list-admin
and is not needed anymore) -> 48 lines less :-)
- add TODO to list_admins() to use AdminHandler
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1282 a1433add-5e2c-0410-b055-b7f2511e0802
- add log action 'edit_alias_domain'
- update outdated comment to point to $action_list instead of
maintaining the list as comment _and_ variable
languages/*.lang
- add $PALANG['pViewlog_action_edit_alias_domain']
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1278 a1433add-5e2c-0410-b055-b7f2511e0802
- rewrite to work for superadmins also (will list all domains now
instead of "ALL"), which means we can drop the admin vs. superadmin
check at various places
- escape_string $username
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1265 a1433add-5e2c-0410-b055-b7f2511e0802
- get_domain_properties(): use DomainHandler (function result mostly
unchanged, only difference: instead of quota_sum in bytes it now
returns total_quota in MB)
- allowed_quota(): adopt to slightly changed return value of
get_domain_properties()
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1248 a1433add-5e2c-0410-b055-b7f2511e0802
- pacol(): new parameter $dont_write_to_db - needed to skip JOINt in
columns which (of course) aren't available on INSERT or UPDATE
model/DomainHandler.php:
- initStruct(): mark JOINt in columns with the dont_write_to_db flag
- store(): skip columns with the dont_write_to_db flag set (not_in_db
columns are also/still skipped)
In non-technical terms: create-domain works now :-)

- use a new SELECT query syntax (sub-SELECTs) that gets all needed
information (including alias count, mailbox count and total quota)
in one query and is fast as light.
Better don't ask how long it took me to write this query, and I
seriously hope it works with postgresql. Otherwise...!
- add alias_count, mailbox_count and total_quota (including the required
SQL magic) to $struct
- add support for funny[tm] query tricks in $struct:
- replacement for field name in SELECT statement
- additional SQL after the FROM xy clause - useful for JOINs
- new function getList($condition) to get a list of domains
- order SELECT results by $this->id_field (needed for getList)
- add comment about the values used in $struct[*][type]
functions.inc.php:
- add two more optional parameters to pacrypt(): $select and $extrafrom
scripts/shells/domain.php:
- display number of existing aliases and mailboxes
- display quota sum

- new function db_where_clause($condition, $struct) to create a WHERE clause.
bool values are converted with db_get_boolean() based on $struct
model/DomainHandler.php - view():
- build WHERE clause with db_where_clause()
- new array $colformat for columns which need special handling in the field list
(that's more readable than tons of elseif on the long term, and allows easier
customization (hook/$CONF value?))
git-svn-id: https://svn.code.sf.net/p/postfixadmin/code/trunk@1228 a1433add-5e2c-0410-b055-b7f2511e0802
- new function db_boolean_to_int() to convert boolean values from the
database to integer (0 or 1)
- db_get_boolean(): error out on unknown $CONF[database_type]

- new config option $CONF['password_validation'] - array with regular
expressions to check if a password is valid/good enough.
The default configuration enforces:
- minimum length 5 characters/digits/whatever
- at least 2 characters
- at least 2 digits
- removed $CONF['min_password_length'] - it's now handled in /.{5}/ in
$CONF['password_validation']
functions.inc.php
- new function validate_password to check a given password against
$CONF['password_validation']
- generate_password: generated password is always 8 chars long
(instead of $CONF['min_password_length'])
edit-admin.php, users/password.php, edit-mailbox.php, setup.php:
- use validate_password instead of $CONF['min_password_length']

functions.inc.php:
- create_admin(): use db_insert instead of INSERT queries
(this includes automatic escaping of all values)
create-admin.php:
- use safepost instead of isset($_POST[...])
- don't escape_string post values - it's done inside create_admin now
- remove superfluous emptying of empty $tDomains for GET
- allow htmlentities-escaping for pAdminCreate_admin_username_text
- some whitespace / linebreak changes
setup.php:
- load config.inc.php only once (loading it twice will break if custom
hook functions exist in config.*.php - "can't redefine function ...")

- integrate field labels, descriptions etc. in $struct
- $struct now has named keys and is filled with the new pacal() helper function
- replaced TODO comments with new ones ;-)

- change default of $CONF['admin_email'] to '' and updated the comment.
IMPORTANT: If set, this will be used as mail sender for all mails
(2.3.x used the currently logged admin's username in most cases).
$CONF['admin_email'] = '' will match the 2.3.x behaviour.
functions.inc.php:
- new function smtp_get_admin_email() to get mail sender address
($CONF[admin_email] or currently logged in admin if not set)

This would have made the debugging session I just had with makomi on IRC

- do not leave the while loop with break - this could hide some
undeliverable alias targets from being flagged if another alias
target points to a domain in $CONF[show_undeliverable_exceptions]
- do not add a blank $CONF[show_status_text] if
$CONF[show_undeliverable] is disabled - it only wastes space ;-)

don't show vacation_domain as undeliverable + various code cleanup
- don't show the vacation domain as undeliverable
In theory this should already have worked already, but $stat_vacdomain
missed the first letter of the domain ("xample.com" instead of
"example.com") which broke it.
Fixed by using $stat_domain, which has the same content anyway.
This fixes part (2) of
https://sourceforge.net/tracker/?func=detail&aid=1951926&group_id=191583&atid=937967
- generate the regex for $CONF[recipient_delimiter] at the start of the
function. Besides saving some CPU cycles, this makes the code more
readable.
- generate $stat_domain earlier and in a regex-free way
- drop $stat_catchall - it's nothing else than @ + $stat_domain
- use in_array() to check $CONF[show_undeliverable_exceptions] instead
of a while loop

- explicitely check for unlimited maxquota when checking if
$quota > $limit[maxquota]. Without this, $quota was always
considered as being too big (not surprising, everything is >0 ;-)
This fixes https://sourceforge.net/tracker/?func=detail&aid=3306926&group_id=191583&atid=937964
(caused by domain quota patch, therefore not affecting 2.3.x)
- replaced setting $rval with return in some cases if the decision is
final without needing to check domain quota
- added lots of comments to make understanding the function easier
