From Thunderbird to Apple Mail
This is actually an old post of mine back at “The Unofficial Mac”. I am reposting for convenience.

One of the reasons I was itching for an upgrade to Leopard had been the new Mail. I have been using Thunderbird as my e-mail client on my Mac from Day 2. On Day 1 I gave a shot and used Apple Mail for a while, but we were not ticking together so I dumped it and switched to good old Thunderbird.
Now I am on Leopard and shiny new Apple Mail is just waiting for me in my Applications folder so I decided it is the correct time to give it a try.
After I set up my e-mail settings through a very simple wizard I chose Import from the File menu and there was Thunderbird. Import took a few minutes and all my e-mail was available in Apple Mail.
There has been a few glitches for the past few days but everything is normal now. The problem was that, and it happens again time-to-time, when I open a folder none of the e-mails there seem to have content. I noticed this when I have searched for a mail that I know existed but received no results. I don’t know the exact cause of the problem, but it gets fixed by itself when I closed and re-opened Mail so I believe it is somewhat related to Mail not being able to process all e-mail (over 10,000) in the first pass.
