Switching from Thunderbird to Apple Mail
Both macOSXHints and mozillaZine carry the same tip for importing email messages into
Contacts can be exported from
You can then import them into OS X’s Address Book using its native import feature or using a third-party app like Address Book Importer (which is free for a “one-off” use).
UPDATE: In the comments to this entry, Andreas Amann points out some problems with the tip on masOSXHints and MozillaZine. He notes that Eudora Mailbox Cleaner now handles the importing of Thunderbird mailboxes as well (and better). Thanks.
Going the other way? (Shame on you!) CosmicSoft’s emlx to mbox converter looks promising for Mail 2.0 users on the way out. Use it, then follow the second half of the instructions for importing emails from kmail in the Thunderbird FAQ.

Unfortunately, this will have several problems:
* Messages which have been deleted in TB might show up in Mail
* All messages will show up as unread
* Some messages might be strung together in a single message in Mail (TB can use EOLs different from what Mail expects, even changing within a single mailbox and/or message)
There is another option to import TB mailboxes to Mail though – use “Eudora Mailbox Cleaner’ (which has been expanded to add this conversion as well):

Why would you want to switch? What’s the use?

“Why would you want to switch? What?¢‚Ǩ‚Ñ¢s the use?”
Thunderbird is a nice program, especially on windows/Linux. OS X Mail however is a better choice for most Mac users. Smart Mailboxes, Keychain support, Address book support, and things like being able to drag messages into closed nested folders come to mind. But there is a lot more.
Keychain support is the biggest reason for me personally not to use it. I will not use a password manager that is not system wide. If they provided that and Address book support I would seriously consider Tbird.

Here is another reason, I just sent the URL of this page to myself. Thunderbird failed to parse it correctly. Mail did it right.

When trying to import Mailboxes in the mbox format (which were originally exportet from Outlook to Thunderbird on my windows machine) in Apple Mail, the app slows down OS X and in the end only imports one message. Thunderbird on Mac OS imports the same mbox files without a problem (using MboxImport) … anyone knows what’s going on?

Benedikt, I would give it a try with Andreas Amann’s Eudora Mailbox Cleaner
. It’s a very clever app.

Thanks man! It worked perfectly.
I really wonder why Apple doesn’t provide more solid importers for their apps (iTunes, Mail, …) for all those willing Windows switchers. I mean it took me 3 days of googling to get all my Windows data onto my Mac.
June 23rd, 2006 at 4:57 pm
That’s good news, although you should thank Andreas not me. :)
I remember that the actual transfer of data was a bit of a pain when I switched three years ago. Yes, it is a puzzle.

I will certainly do that. It’s just that without your little hint I’d never thought that an app called “Eudora Mailbox Cleaner” would help me to import Mails from Thunderbird to Apple Mail.

What about Thunderbird filters into apple Mail rules?
I use thunderbird as my email client, and I plan on continuing that I think.
The reason I wish to import my filters as rules, is that the apple mail settings are syncd to my new iPhone from work. But when mail comes to me via iMap on my phone rather then in thunderbird on any mac I have the emails are not properly filtered into the right folder, and then even on thunderbird unless I manually apply filter to folder it stays in the inbox.

I see no one’s replied to Rich’s comment: this is the only reason I haven’t made the switch–because I can’t import my numerous filters on Thunderbird into Apple Mail.

Does this import the mail server and account settings as well, or just the emails?
If just the emails, is there a way to import the mail server and account settings?
Cheers,
Graham.

Thunderbird filters for mail..
I want to move to apple mail because the “send” capabilty on applications, which opens a new email message and attaches the document to the message does not work for thunderbird under OS X 10.4/5. Plus, attachments in messages cannot be moved and opened from the email message independantly without a dialog.
But, the problem is.. how do I move my filters from thunderbird to mail?
Any thoughts?

Hi,
I’m switching from PC to Mac, and as many of you above have been having problems with my mail: like Benedikt only one message came over i each folder (!). I´m trying with Eudora Mailbox Cleaner, and it’s taking long time. Is that how it should be? (it’s been going on for an hour now). I draged the whole mail folder (imported from windows mail to thunderbird in my PC).
Thankfull for any further advise on how exactly I should do!

IT NOW WORKED!!
It took one and a half day for Eudora mailbox Cleaner to go through my imported profile mail file (Thunderbird imported from Windows Mail). Then something started to happen (it happen all the time but I wasn’t sure of it ;o)). Then all my mailbox folders were in Apple Mail – BUT the were all empty!
I found an italian blog describing how well Eudora Mbx Cleaner had worked AND describing that you had to go in each imported mailbox and “rebuild” it (Mail menu: mailbox>rebuild>) And all the messages appeared!!
Thanks for such a good application!! what coukd be improved is the “how-to-go” step by step, for us non-computer-geniuses… ;o)
