Mac Mail deleting messages

[treeman]

So this has happened twice now, about a month apart. One day my inbox has 3500 messages in it, then the next day it only has 300. I'm using IMAP and the messages are also missing from the server end.

Fortunately I'm using Time Machine, so I can get them all back and also see exactly what day they disappear, but obviously its a pain having to upload 3000 + messages every month.

Any ideas whats going on?

Thanks

is it always after the same amount of days?

Possibly a another client you use that by accident is set to POP3 (plus remove from server) instead of IMAP?

From experience or an educated guess? though I'll do it anyway, worth a try, thanks.

This is the second time its happened, about 28 days apart.

I don't think so as I'd never tick the delete from server option, i'll look into it though, thanks.

You could try using a different mail client, such as Thunderbird, and see if it still happens.
