Hi everyone, I went through many forums about this issue, still I didn't find any solution.
I have a server on a public IP, still behind a firewall. Relevant ports are open to the world, like 25, 7071, 80, 443.
I have a fresh open source Zimbra installation:
Release 7.1.3_GA_3346.UBUNTU10_64 UBUNTU10_64 FOSS edition.
mydomain.com has address x.x.x.x
mydomain.com mail is handled by 10 mail.mydomain.com
I try to send a test email to my fresh installation, I get back this:
The mail system
<firstname.lastname@example.org>: host mail.mydomain.com[x.x.x.x]
said: 554 Relaying denied. (in reply to RCPT TO command)
I also tried to add another domain, with mx and a records set in the admin console, I get back totally the same error. Also tried to use multiple servers to send mail to my zimbra server, I got the same problem.
in zimbra.log I only have this:
Nov 4 21:05:23 myhost postfix/smtpd: connect from anotherdomain.com[y.y.y.y]
Nov 4 21:05:23 myhost postfix/smtpd: disconnect from anotherdomain.com[y.y.y.y]
Anyone have any clue about this issue? I'm starting to wonder if that could be maybe a 7.1.3 bug or something.
