Reference bug: http://bugzilla.zimbra.com/show_bug.cgi?id=32740
Zimbra allows relaying emails to a specific server only, i.e using zimbraMtaRelayHost. However, there are needs to relay emails per domain basis. For example, you want emails sent by users@domain1.com should be relayed through smtp.domain1.com and users@domain2.com through smtp.domain2.com servers. You can configure it using "sender_dependent_relayhost_maps".
This is an example and tested on ZCS 5.0.16
1. Add following line to /opt/zimbra/postfix/conf/main.cf
sender_dependent_relayhost_maps = hash:/opt/zimbra/postfix/conf/bysender
2. Create file /opt/zimbra/postfix/conf/bysender and enter your domain names and relay server's IP addresses.
@domain1.com [10.10.10.1] @domain2.com [20.20.20.1]
3. Create the hash file.
postmap /opt/zimbra/postfix/conf/bysender
4. Change the permissions.
chown root.postfix /opt/zimbra/postfix/conf/bysender /opt/zimbra/postfix/conf/bysender.db
5. Restart zmmtactl
zmmtactl stop zmmtactl start
6. Test by sending emails.
Note: Above settings will not survive zimbra upgrades. Make sure you take backup of config files before upgrading.
