For some reason your client programs get out of sync with the server and mix up messages. This is most likely to happen if Mercury is restarted while the IMAP client is connected. If it happens in other circumstances check all the usual problem sources (disk errors, heavy fragmentation, other processes such as anti-virus programs interfering with Mercury's file access) on both client and server systems.

Note that in cases like this no data has been mixed up on the server, the mix up is in the client. 

If mailboxes are only accessed via IMAP you could try switching on lingering mailboxes in Mercury core configuration / Files / Foldering subsystem settings and see if that makes any difference.

Hi all,

ever since the upgrade to 4.72, my inbox gets corrupted when I move messages to another folder. What happens, is that in the message-list, some e-mails show up twice - when I open one, it appears to be a different message. After a "Rebuild index" in my mail -client, the message list is OK again. The same behavior can be seen in Thunderbird 2.0.0.23 as well as SquirrelMail 1.4.3.a . I'm quite sure I didn't have these issues with the previous version of Mercury (4.71), or at least, not this often.

Set-up: Mercury on Windows 2000, 1 mailbox with 3.6 GB data / 560 folders. The inbox usually has no more than 20 messages (I'm quite strict with archiving every mail - in and out - according to sender/subject/project/whatever).

Has anyone else experienced this? Any suggestions on how to deal with it?

Thanks,
