Hey all,

we have installed the Zimbra Collaboration Suite 5.0 - Open Source Edition on a openSUSE 10.2 inkl. Plesk 8.2.

We solved our first problem to configure Zimbra to work parallel with Plesks qmail sucessfully, while changing Ports to 725, 7110, 7..., 7... And now we fetch the emails with POP3 from the Plesk Email accounts. Without Problems.
And until today the Webmail worked fine.

(Always looking in your forum for the right solution. So you all helped us already.)

But now we have a strange problem: We can't send emails through the Webmail.

Always the same error:

No error in zimbra.log but the mailbox.log shows this error:

The last thing we were changing before the error appeared, was to change some authentication settings in the MTA. We rolled this settings back, but the error still appeared.

Sending emails with e.g. Thunderbird through Smtp works still fine.

Please help.

Thanks,

Valentin
