Original-Recipient / Final-Recipient Postfix Issue

[selfxp]

Hi! I have installed ISPConfig with Postfix on Suse. Everything worked fine till this evening when I could't receive any email on any of my email accounts. (I've deleted some old elements from recicle bin and added some new co-domains to a webpage - not sure how this influenced postfix...)

Error message:

This Message was undeliverable due to the following reason:

Each of the following recipients was rejected by a remote mail server.
The reasons given by the server are included to help you determine why
each recipient was rejected.

Recipient: <web7_admin@selfxp.com>
Reason: <web7_admin@selfxp.com> No such user here


Please reply to <Postmaster@chello.at>
if you feel this message to be in error.

Original-Recipient: rfc822;admin@rossik.eu
Final-Recipient: RFC822; <web7_admin@selfxp.com>
Action: failed
Status: 5.1.1
Remote-MTA: dns; mail.selfxp.com (209.132.244.249)
Diagnostic-Code: smtp; 550 <web7_admin@selfxp.com> No such user here

Actually I'm tring to send the message to admin @rossik.eu, why do I have a final recipient with @selfxp.com?
It is true that selfxp.com is my default postifx hostname but why does it sent it there?
postconf -e 'myhostname = selfxp.com

Please help as all my emails get lost on the way...

Thanks a lot!

Thats normal and it is correct that the email is delivered to the hostname of your server. Please check that selfxp.com is listed in the file /etc/postfix/local-host-names and that a linux user with the username web7_admin exists in /etc/passwd
