As someone else already replied, the problem is with the smtp_relay_restrictions or smtp_recipient_restrictions. > And here is what happens when I send mail from the commandline: > > Oct 1 14:11:42 localhost postfix/pickup[3995696]: 44C4416239C: uid=1000 > from=<usernam> But when you use the command line, the mail enters Postfix via the pickup service. That’s completely different from smtpd (that’s the SMTP daemon). Command line works because having the mail enter via pickup does not use the bad smtpd_…_restrictions parameters. -- Larry Stone lston...@stonejongleux.com
