Many users of Zimbra may want to integrate Request Tracker (RT) or Mailman, both of which are typically configured by executing scripts from /etc/aliases. With Zimbra 5, /etc/aliases appears to be mostly ignored and therefore cannot be used. This wiki entry is based on a trick that was figured out in this forum post.
This wiki entry is also confirmed to work for ZCS 6.x.
Steps for integrating RT
0. Make sure you're user Zimbra
$ su - zimbra # su - zimbra
In the first case you may have permissions problems; in the second, your $PATH will be suboptimal.
1. Configure the Postfix main.cf to handle an additional transport map Execute the following command:
zmlocalconfig -e postfix_transport_maps=' hash:/opt/zimbra/postfix/conf/transport,ldap:/opt/zimbra/conf/ldap-transport.cf'
This will add /opt/zimbra/postfix/conf/transport as an additional transport map.
2. Create the transport map
Edit /opt/zimbra/postfix/conf/transport and place the following lines at the top:
# Pipe transports for RT queues # YOU HAVE TO ADD THE PIPES TO /opt/zimbra/postfix/conf/master.cf if you want them to work!!! firstname.lastname@example.org rt-pipe email@example.com rt-comment-pipe
And then create the transport db by executing (as zimbra)
3. Define the pipe transports
The transport definitions 'rt-pipe' and 'rt-comment-pipe' must now be defined. Edit /opt/zimbra/postfix/conf/master.cf.in and add the following lines to the end of the file:
rt-pipe unix - n n - - pipe flags= user=www argv=/opt/rt3/bin/rt-mailgate --queue general --action correspond --url http://rt.example.com/ rt-comment-pipe unix - n n - - pipe flags= user=www argv=/opt/rt3/bin/rt-mailgate --queue general --action comment --url https://rt.example.com/
Note that the 2nd line needs to be right under the first and must start with whitespace, and the first line cannot start with whitespace or postfix will fail with 'unexpected command-line argument' errors. Also make sure the user= line is pointing to a valid user with permissions to execute the script. This user must not be the postfix or root user or the pipe will fail.
4. Restart Postfix and test
Execute the following commands:
zmmtactl stop ; zmmtactl start
Now, you should be able to email firstname.lastname@example.org and receive a message back. grep for RT in /var/log/messages as well as tail /var/log/mail to watch for errors.
