Hello Till

SOLVED: I had to remove the domain from mydestination in PostFix then reload PostFix- ALL IS GREAT THANK YOU VERY MUCH!

EDIT 2: It appears that ALL E-Mail being sent to the domain '' is seeing a response from PostFix OR ISPConfig claiming 'unknown user' at the domain

After regaining access to SquirrellMail I logged into a users account and sent an E-Mail out to one of my Gmail accounts successfully.

From Gmail however when I try to reply I receive an error notice:

<>: unknown user: "usermagic"

Final-Recipient: rfc822;
Original-Recipient: rfc822;
Action: failed
Status: 5.1.1
Diagnostic-Code: X-Postfix; unknown user: "usermagic"

I tailed '/var/log/mail.log' while Gmail attempted sending to the server- following is the results of that:
Jun  3 17:47:00 giganetwireless postfix/smtpd[25291]: connect from[]
Jun  3 17:47:01 giganetwireless postfix/trivial-rewrite[25312]: warning: do not list domain in BOTH mydestination and virtual_mailbox_domains
Jun  3 17:47:01 giganetwireless postfix/smtpd[25291]: D3273B8C1E8:[]
What could be the cause of this strange behaviour?

Thank you for your suggestions.

Best Regards
