Posted by On previous post, we can relay email based on user/domain receiver. But, on this guidance is reverse from previous post. ie the relay based on user/domain sender. Zimbra supported for multi domain. You can have many domain in one Zimbra server. I have condition where either domain cannot sending to some domains. For example, i have 2 domains in Zimbra server, domain1.com and domain2.com.
domain1.com can sending email to domain3.com but domain2.com cannot sending email to domain3.com. Whereas domain1.com and domain2.com are in one Zimbra server. it is rather strange indeed. For be able sending to domain3.com from domain2.com, i am decide to relay every sending email from domain2.com. For do that, i do the following guidance
# Add the following configuration in /opt/zimbra/postfix/conf/main.cf
sender_dependent_relayhost_maps = lmdb:/opt/zimbra/postfix/conf/bysender
# Create file above and adding users/domains would be relay
vi /opt/zimbra/postfix/conf/bysender
Fill as the following example
@domain2.com [relay.example.com] user1@domain1.com [relay.example.com]
configuration above will do relay every sending email from @domain2.com and user1@domain1.com to relay server at relay.example.com
# Postmap file
postmap /opt/zimbra/postfix/conf/bysender
# Reload Postfix
postfix reload
Note : every add/delete users/domains in /opt/zimbra/postfix/conf/bysender, don’t forget to postmap and reload postfix
Good luck and hopefully useful 😀
doesnt working for me . I have a global smtp configured already on zimbra 8.6

Please help 🙂
Hi Suvro,
Are you have been doing postmap?
Hello this is great but I seem to have a problem:
postconf -n | grep bysender
sender_dependent_relayhost_maps = lmdb:/opt/zimbra/postfix/conf/bysender
ls -lsa /opt/zimbra/postfix/conf/bysender.lmdb
20 -rw-r–r– 1 zimbra zimbra 20480 Dec 15 17:30 /opt/zimbra/postfix/conf/bysender.lmdb
cat /opt/zimbra/postfix/conf/bysender
@mydomain.fr [10.42.0.40]
postfix reload

Still I see the messages going by the mx record for the domain.
Hi,
Please try to restart your Zimbra (su – zimbra -c “zmcontrol restart”) instead of postfix reload
Hello Iman,
I have similar “problem”. I like to send mail from my zimbra (8.6) to gmail account but thru smtp.gmail.com,
I will do all command above but I am not clear how can I authenticate to SMTP.GMAIL.COM?
..and if I do steps from previous for authentication post I am afraid that all mail will go thru google … not sure how to combine these two 🙂
Thank you if you have time to answer
Hi Alex,
You can combine with this one : https://imanudin.net/2014/09/18/how-to-configure-outgoing-smtp-authentication-on-zimbra-8-5/. Skip run command in this one
Now, you can configure relay based on user/domain sender 🙂
/opt/zimbra/common/conf/main.cf
To the Last Line of the File
sender_dependent_relayhost_maps = lmdb:/opt/zimbra/common/conf/bysender
Added
/opt/zimbra/common/conf/bysender
Into the File
mahbubarice.com.tr [10.10.50.62:25]
I made the same definition more than once
su zimbra
postmap /opt/zimbra/common/conf/bysender
postfix reload
I applied
I Provided The Identification Process,
Mail When I Test It Only Does Not Reach Through Mail Gateway,
Direct Zimbra Sending on Server,
What I Want is to Deliver Mail After Passing Through PMG ?
Where am I doing wrong ?
Hi Halil Ibrahim Ayhan,
As I know, PMG uses port 26 for a relay. Please change your relay so that like below
