Hi, I'm new to qmail so I don't know how to solve the problems above. We have about > 1000 users who access their mailboxes through qmail-pop3d. All this day, none of the e-mail go to their mailboxes which is in a mail directoy. maillog says: Jul 11 11:42:31 www qmail: 963286951.551808 delivery 4: deferral: Unable_to_swit ch_to_/home/mailhome/a/aim:_access_denied._(#4.3.0)/ Jul 11 11:42:31 www qmail: 963286951.556969 status: local 2/10 remote 4/20 Jul 11 11:42:31 www qmail: 963286951.561328 delivery 6: deferral: Unable_to_swit ch_to_/home/mailhome/a/aileen:_access_denied._(#4.3.0)/ Jul 11 11:42:31 www qmail: 963286951.565217 status: local 1/10 remote 4/20 Jul 11 11:42:31 www qmail: 963286951.576043 delivery 8: deferral: Unable_to_swit ch_to_/home/mailhome/d/din91:_access_denied._(#4.3.0)/ .... and so on...
