New on Groupwise systems, so I hope to make a shortcut here.

Problem: When we restart our post office, an old message (with attachment) from one of our clients pops up in recipients mail boxes.

We asked our client to delete all traces of the mail from his mailbox, but after a restart today (kernel update) same thing happened.

I suspect this mail is hidden in some of the many queues in the groupwise system, but where? All advice is welcome.
