About Virtual Vacation
|
|
|
|
|
----------------------
|
|
|
|
|
Virtual 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.
|
|
|
|
|
The vacation script runs as service within Postfix's master.cf configuration file.
|
|
|
|
|
Mail is sent to the vacation service via a transport table mapping.
|
|
|
|
|
When users mark themselves as away on vacation, an alias is added to their account
|
|
|
|
|
sending a copy of all mail to them to the vacation service.
|
|
|
|
|
|
|
|
|
|
e.g. mail to billy@goat.com will be delivered to
|
|
|
|
|
billy@goat.com AND
|
|
|
|
|
billy#goat.com@autoreply.goat.com
|
|
|
|
|
|
|
|
|
|
Mail to @autoreply.goat.com is caught by the vacation.pl script and a reply
|
|
|
|
|
will be sent based on various settings. By default a reply is only sent once.

4. Setup the transport type
|
|
|
|
|
--------------------
|
|
|
|
|
---------------------------
|
|
|
|
|
Define the transport type in the Postfix master file:
|
|
|
|
|
|
|
|
|
|
#/etc/postfix/master.cf:
|
|
|

5. Setup the transport maps file
|
|
|
|
|
--------------------------------
|
|
|

Tell Postfix to use a transport maps file, so add the following to your

Postfix main.cf:

The database table should have already been created for you, by running

the 'upgrade.php' script when installing Postfixadmin.

7. Check the alias expansion
|
|
|
|
|
----------------------------
|
|
|
|
|
|
|
|
|
|
Depending on your setup, you may have multiple 'smtpd' service definitions within
|
|
|
|
|
your postfix master.cf file. This is especially the case if you are also using AMAVIS or
|
|
|
|
|
another content filtering system when mail is re-injected into Postfix using the smtpd daemon.
|
|
|
|
|
|
|
|
|
|
If you are, it's likely that alias expansion may happen more than once, in which case you
|
|
|
|
|
may see vacation-style responses duplicated. To suppress this behaviour, you need to add :
|
|
|
|
|
|
|
|
|
|
-o receive_override_options=no_address_mappings
|
|
|
|
|
|
|
|
|
|
For example :
|
|
|
|
|
|
|
|
|
|
smtp inet n - - - 12 smtpd
|
|
|
|
|
-o content_filter=amavis:[127.0.0.50]:10024
|
|
|
|
|
|
|
|
|
|
^^^ Alias expansion occurs here, so we don't want it to happen again for the other smtpd daemon (below)
|
|
|
|
|
which receives email out of amavis on port 10025.
|
|
|
|
|
|
|
|
|
|
127.0.0.1:10025 inet n - - - - smtpd
|
|
|
|
|
-o smtpd_autorized_xforward_hosts=127.0.0.0/8
|
|
|
|
|
-o smtpd_client_restrictions=
|
|
|
|
|
-o smtpd_helo_restrictions=
|
|
|
|
|
-o smtpd_sender_restrictions=
|
|
|
|
|
-o smtpd_recipient_restrictions=permit_mynetworks,reject
|
|
|
|
|
-o mynetworks=127.0.0.0/8
|
|
|
|
|
-o receive_override_options=no_unknown_recipient_checks,no_header_body_checks,no_address_mappings
