PSA v7.0.2 on one (and only one) domain, i get 'over quota' behaviour on all mailboxes once there's 2Mb in the mailbox, WHATEVER the mailbox quota is set at. when the domain was first set up on in PSA, the default mailbox quota WAS, in fact, set at 2Mb. it was later increased to 20Mb. has anyone else had this experience? any suggestions (other than deleting the domain and starting again)?
