    We are running Plesk 12.5.30 Update #45.

    This morning mailman was not able to deliver email to any of our distribution list. The Postfix configuration was updated last night which seemed to cause the problem. The issue has to do with case folding between mailman and postfix as described here in 2010: .

    The solution is to add the case folding flag into
    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}

    Note the "u" in the flags option, which folds the recipient name to lowercase.
    All is working fine after this change.

    Would it be possible to review and integrate this change into Plesk so others don't find this issue?

    Thanks, Greg
