All of a sudden this morning everyone using one of our QMT7 mailservers has started getting 6,7,8 copies of each email. This is with IMAP accounts. It seems as if the mailserver is not registering or marking the emails that they have already been downloaded. I checked and we don't have multiple copies on the mailserver itself - just on the email clients that connect to it.
Any ideas ? Everything was working fine until this morning. Regards, Jeff
