[MzaNike]

07-11-27 23:31:37 xx.xx.xx.xx POPS mydomain.de xx.xx.xx.xx 304 RETR RETR+1 -ERR+Message+unavailable HOSTNAME 0 8 32 user@mydomain.com


This is a message, which I do find in the W3C Logs of the POP-Service.
The User can access Webmail and access his mails, but is getting the error above, when trying to doanload them via Outlook,

I do not get it fixed (neithir with repair or installing MailEnable fixes (I am using Standard 1.981).
Other Domains are running fine.

The Diagnostic gives me the following warnings:
POP Retrieval Connector (None) Status: Service Not Installed ||WARN


Dont know what to do further..any Ideas?

Thanks
Michael

Hello

thanks for your reply, I already found the problem, but forget to post it here.
There has been activated "run task" on the mailbox, but nothing behind it, so reactivated av-scanning and it worked.

Thanks for your help!!!
