Vanishing sent messages in Apple Mail 4.3
If the message was a reply, I can't find it back by clicking on the curly arrow next to the name of the original message. A friend also experienced the same problems and we unfortunately can't replicate or find a logic to this bug. Searching doesn't do the trick, I'm using IMAP and it's also gone on the server but people receive these messages apparently.
Technote: MailTags and Mail Act-On are installed.
Has anyone experience the same problem and manage to isolate the cause of it? Thanks in advance for your help.
MacBookPro, Mac OS X (10.6.4)
