Thank you Viktor. For clarification purposes I'll attach the output of postconf: http://pastebin.com/PBg04yBE I removed the override from default append_dot_mydomain = yes and tried to send mail from my www jail. This is what was logged: Apr 28 18:58:06 mail postfix/smtp[6078]: 7D3424207: to=<r...@www.blmbrg.de>, orig_to=<root@www>, relay=www.blmbrg.de[94.79.159.82]:25, delay=0.24, delays=0.13/0/0.11/0, dsn=5.4.6, status=bounced (mail for www.blmbrg.de loops back to myself) I have reverted this change after seeing this. Does this mean we are on to something? Sebastian
