messaging server 4.1: POP3 users received several copies of the messages

It seems that stored don't remove the messages and the users get a lot of copies of the same messages...

Do any of the users have "Leave copy of message on server" in their mail client preferences?

Also has a reconstruct -r been tried?

If it has not I recommend running one on the entire store. This will fix any problems with the mailbox index files which could be causing this problem.
