About Virtual Vacation
|
|
|
|
|
----------------------
|
|
|
|
|
Virual Vacation is today done with a local shell account that can receive
|
|
|
|
|
email. The email is then handled by a Perl script which sends the Vacation
|
|
|
|
|
message back to the sender.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Install Virtual Vacation
|
|
|
|
|
------------------------
|
|
|
|
|
|
|
|
|
|
1. Create a local account
|
|
|
|
|
-------------------------
|
|
|
|
|
Create a dedicated local user account called "vacation".
|
|
|
|
|
This user handles all potentially dangerous mail content - that is why it
|
|
|
|
|
should be a separate account.
|
|
|
|
|
|
|
|
|
|
Do not use "nobody", and most certainly do not use "root" or "postfix". The
|
|
|
|
|
user will never log in, and can be given a "*" password and non-existent
|
|
|
|
|
shell and home directory.
|
|
|
|
|
|
|
|
|
|
This should look like this:
|
|
|
|
|
|
|
|
|
|
#/etc/passwd
|
|
|
|
|
vacation:*:65501:65501::0:0:Virtual Vacation:/nonexistent:/sbin/nologin
|
|
|
|
|
|
|
|
|
|
#/etc/group
|
|
|
|
|
vacation:*:65501:
|
|
|
|
|
|
|
|
|
|
2. Create a directory
|
|
|
|
|
---------------------
|
|
|
|
|
Create a directory, for example /var/spool/vacation, that is accessible
|
|
|
|
|
only to the "vacation" user. This is where the vacation script is supposed
|
|
|
|
|
to store its temporary files.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
3. Copy the files
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
Copy the vacation.pl file to the directory you created above:
|
|
|
|
|
|
|
|
|
|
$ cp vacation.pl <HOME>/vacation.pl
|
|
|
|
|
$ chown -R vacation:vacation <HOME>
|
|
|
|
|
|
|
|
|
|
Which will then look something like:
|
|
|
|
|
|
|
|
|
|
-rwx------ 1 vacation vacation 3356 Dec 21 00:00 vacation.pl*
|
|
|
|
|
|
|
|
|
|
4. Setup the transport type
|
|
|
|
|
--------------------
|
|
|
|
|
Define the transport type in the Postfix master file:
|
|
|
|
|
|
|
|
|
|
#/etc/postfix/master.cf:
|
|
|
|
|
vacation unix - n n - - pipe
|
|
|
|
|
flags=Rq user=vacation argv=/var/spool/vacation/vacation.pl -f ${sender} -- ${recipient}
|
|
|
|
|
|
|
|
|
|
Tell Postfix to use a transport maps file, so add the following to your
|
|
|
|
|
Postfix main.cf:
|
|
|
|
|
|
|
|
|
|
#/etc/postfix/main.cf:
|
|
|
|
|
transport_maps = hash:/etc/postfix/transport
|
|
|
|
|
|
|
|
|
|
Then add the transport definition to the newly created transport file.
|
|
|
|
|
Obviously, change yourdomain.com to your own domain. This can be any
|
|
|
|
|
arbitrary domain, and it is easiest if you just choose one that will be used
|
|
|
|
|
for all your domains.
|
|
|
|
|
|
|
|
|
|
#/etc/postfix/transport
|
|
|
|
|
autoreply.yourdomain.com vacation:
|
|
|
|
|
|
|
|
|
|
Execute "postmap /etc/postfix/transport" to build the hashed database.
|
|
|
|
|
|
|
|
|
|
Execute "postfix reload" to complete the change.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
5. Create the table
|
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
|
|
See DATABASE.txt in this directory.
|
|
|
|
|
|
|
|
|
|
6. Edit filter.pl
|
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
|
|
The perl filter.pl script needs minor modification to know which database
|
|
|
|
|
you are using, and also how to connect to the database.
|
|
|
|
|
|
|
|
|
|
Namely :
|
|
|
|
|
|
|
|
|
|
Change any variables starting with '$db_' and '$db_type' to either 'mysql' or 'pgsql'.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
What do these files do?
|
|
|
|
|
-----------------------
|
|
|
|
|
When a user enables a vacation message on their account, the alias
|
|
|
|
|
definition is changed so that in addition to delivering to their own
|
|
|
|
|
mailbox, it also delivers to a dummy alias which calls the vacation.pl
|
|
|
|
|
program. In other words, if joeuser@domain.com enables their vacation, the
|
|
|
|
|
entry in the alias database table will deliver mail to
|
|
|
|
|
joeuser@something.com, as well as
|
|
|
|
|
joeuser@something.com@autoreply.yourdomain.com
|
|
|
|
|
|
|
|
|
|
vacation.pl then checks the database to see wether a user is on holiday and
|
|
|
|
|
what message to send back. Make sure that vacation.pl is able to communicate
|
|
|
|
|
to your databse. In the first couple of lines you have to specify the
|
|
|
|
|
database, username and password for it.
|
|
|
|
|
NOTE: Make sure that the path to perl is correct.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
I'm in trouble!
|
|
|
|
|
---------------
|
|
|
|
|
When something is not working there are a couple of files that you can have
|
|
|
|
|
a look at. The most important one is your maillog (usually in /var/log/).
|
|
|
|
|
|
|
|
|
|
Vacation.pl also has some debugging and logging capabilties. Check the top
|
|
|
|
|
of vacation.pl.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
Done!
|
|
|
|
|
-----
|
|
|
|
|
When this is all in place you need to have a look at the Postfix Admin
|
|
|
|
|
config.inc.php. Here you need to enable Virtual Vacation for the site.
