HELP! Mac Mail Lost Messages When I Upgraded to Leopard!
Not actually. Although at first it appears that way.
This is the setup that causes this to happen:
Mac OSX 10.4.x
MacMail
SpamSieve email filter with folder named “spam” that is “on my mac”.
Everything works fine with this setup. No issues.
You upgrade to Leopard and suddenly, it appears you have no email.
What happens: Apple mail, when you upgrade to Leopard removes all plugins. This includes SpamSieve. When that happens, all your mail messages — spam and not spam — are dumped into your spam folder that you created for SpamSieve.
The solution: reinstall the SpamSieve plugin and manually move your messages from the spam folder to your inbox.
This is a great post explaining exactly how to do that
By the way, if you don’t use SpamSieve, it is the BEST spam filter ON THE PLANET!
