    Sep 26 19:04:52 web-11 postfix/pipe[2182]: 8923B1F68003: to=<>, relay=mailman, delay=0.16, delays=0.01/0/0/0.16, dsn=5.3.0, status=bounced (Command died with status 1: "/usr/lib64/plesk-9.0/postfix-mailman". Command output: post script, list not found: SVO_VOs )


Mailman creates maillist directory in lowercase on the disk and when it checks for the existence of the list, it checks in lowercase. "Ru" flag is reset to "R" in /etc/postfix/ This is Plesk internal issue with ID #PPPM-245, that is planned to be fixed in future Plesk updates.


Change the following line in /etc/postfix/


mailman unix - n n - - pipe flags=R user=mailman:mailman argv=/usr/lib/plesk-9.0/postfix-mailman ${nexthop} ${user} ${recipient}


mailman unix - n n - - pipe flags=Ru user=mailman:mailman argv=/usr/lib/plesk-9.0/postfix-mailman ${nexthop} ${user} ${recipient}
