forwarding loop with usernames with @

Hi!

I have a problem in Postfix with usernames in the form user@domain. Having set a .forward from Usermin including the "Normal user mailbox" option, I receive the following email back when trying to send messages to that address:

Final-Recipient: rfc822; mikrub-xintai.de@sistine.alambitco.com
Original-Recipient: rfc822; mikrub@xintai.de
Action: failed
Status: 5.0.0
Diagnostic-Code: X-Postfix; mail forwarding loop for
mikrub-xintai.de@sistine.alambitco.com

The .forward looks like that:

\mikrub@xintai.de
"|/etc/usermin/forward/autoreply.pl /home/domains/xintai.de/homes/mikrub/autoreply.txt mikrub@xintai.de"

I tryied editing the first line manually to:
\mikrub-xintai.de

and the message gets delivered properly.
Am I missing some settings?
If not, that's a bug and it could be fixed letting Usermin automatically generate a "Normal user mailbox" like I did.

Please let me know...
Ciao!
Michele
