Hi all,

I have an odd new problem to deal with since we upgraded from 4.5.9 to 5.0.1 (NE) last week.

Any user who receives another users mail by a forward, as well as a copy directly to them, is receiving the same mail twice; for example, my boss receives all the staff emails within the department, so any new support ticket notifications or the like are sent to all of us, and he receives that mail 5 times. This didn't happen in 4.5.9.

Does anybody have any idea where to look? I've been though zimbra.log, and all seems well there. mailbox.log shows rather more LMTP transfers than would be normal for affected accounts (by a factor of between 2 and 4) but I wouldn't have the first idea where to address this. Is it a setting that may have changed between versions?

Any help appreciated!
