Hi all, I'm reading this guide on the wiki and I susccesfly set up and smtp rely for my server.
Now I have a problem. I have to set an imap external account (and that's easy). This account has to send mails by another smtp.
The smtp it has to use is smtps.pec.aruba.it.
So, all the mail sent from my zimbra server still have to go out by smtp.example.com, but this external account has to use smtps.pec.aruba.it.
In zimbra administration/server/MTA, I see I can add an MRA, but no clue how to continue.
