I'm running zimbra from a quite bit long but I hasn't realise that I was issuing a configuration problem.
Time to times, some mail server reject my email. After looking around, I've seend that the mail sender server (mine) is in fact localhost and not my FQDN mail server.
How and where can I correct this ?
By the way, I'm running 2 domains on my Zimbra config.
Thx in advance.
