I've been using Mail.app to read my email since 1992 or so, back when it was called NeXTmail. I'm generally pleased with it. Lately, though, I've been having a problem with the IMAP implementation, and specifically with Dreamhost. The problem that I'm having is that Mail.app sometimes doesn't notice when new mail is added to a mailbox, and the only thing I can do is "rebuild" the mailbox. This is a problem. Why does it happen? Is there an email provider that doesn't have these problems?
Well, gmail doesn't have the problem, but it has bother problems.
So I would like to understand why this is happening and what I can do about it. Is there an IMAP server that's better than Courier (which is what Dreamhost is using)? Thanks
