pyvacation

Postfix python autoresponder

Pyvacation is a simple python autoresponder for the Postfix Mail Server.

INSTALLATION

1. Copy pyvacation into Postfix configuration

~# mkdir /etc/postfix/autorespoder ~# cp pyvacation.py /etc/postfix/autoresponder/

2a.

~# vim /etc/postfix/master.cf #add these lines autoreply unix - n n - - pipe flags= user=vacation argv=/etc/postfix/autoresponder/pyvacation.py --deliver ${sender} -- ${recipient} autoreplyCmd unix - n n - - pipe flags= user=vacation argv=/etc/postfix/autoresponder/pyvacation.py --autoreply ${sender} -- ${recipient}

2b.

~# vim /etc/postfix/main.cf

uncomment or add this line

transport_maps = hash:/etc/postfix/transport

add autoreply_virtual to the virtual_alias_map lookup tables

virtual_alias_maps = hash:/etc/postfix/virtual, hash:/etc/postfix/autoreply_virtual

Add to /etc/postfix/virtual :

autoreply@your-domain [email protected]

Add to /etc/postfix/transport :

autoreply.yourdomain autoreply: autoreplyCmd.yourdomain autoreplyCmd: gotreply.yourdomain tracker_reply:

Create the file "autoreply_virtual" in /etc/postfix

~# touch /etc/postfix/autoreply_virtual

If you have SELINUX enabled you are needed to add a police for the autoresponder to work properly. I'm using this one:

module vacationpolicy 1.0;

require { type tmp_t; type postfix_pipe_t; type postfix_spool_t; type postfix_etc_t; type postfix_map_exec_t; class dir { write remove_name add_name read search }; class file { write create unlink getattr append execute execute_no_trans read }; }

#============= postfix_pipe_t ============== allow postfix_pipe_t postfix_spool_t:dir { write remove_name add_name }; allow postfix_pipe_t postfix_spool_t:file { create unlink }; allow postfix_pipe_t postfix_map_exec_t:file { execute getattr execute_no_trans read }; allow postfix_pipe_t tmp_t:dir { read write search add_name remove_name }; allow postfix_pipe_t tmp_t:file { create unlink getattr }; allow postfix_pipe_t postfix_etc_t:file { append write };
