Hi All,

Been using Zimbra now for a long time and just recently started to implement it on a new server.

I have installed version 7 but am experiencing a problem. Whenever i send a email i see in the logs the following

Jan  2 00:01:16 mail postfix/smtp[7528]: C000746209F: to=<xxxx@xxx.com>, relay=mail2.xxxxxxxxx.nl[xx.xx.xxx.xx]:25, delay=0.11, delays=0.01/0/0.09/0.01, dsn=4.1.7, status=deferred (host xxx.xxxxx.xxx[xx.xx.xx.xx] said: 450 4.1.7 <user@hide-out.net>: Sender address rejected: unverified address: connect to mail.hide-out.net[xxx.xxx.xx.xxx]:25: Connection refused (in reply to RCPT TO command))
Strange thing is if i send a message to the unverified address that it just arrives within zimbra.

Since i am behind a firewall and i forward the information to my old zimbra server it all seems to work just fine. I have no idea what the problem can be.

Hopefully somebody can help me on this.

Thanks in advance.
