emlx to mbox converter will convert your individual emlx mail files (found in ~/Library/Mail/) to the old mbox format, used by almost every UNIX/Linux mail client and recognized by many more.

With this tool, you could convert some individual emlx files to mbox and then import the mbox file using Mail for Mac OS X or almost any other mail client.

  • Improves performance and now supports "partial" emlx files.

This tool still works as of January 2010 and has just saved me.

Mail wouldn't import a folder backup I made of my mail. After Mail crashed several times while trying to import I used this tool convert the emlx files to one big mbox file - and it worked flawlessly. (Exept from some empty mails - approx. the number of mails that I imported - that I just had to delete.) Even my MailTags comments and stuff were preserved!

Big thx!

This tool very easy to use, but it didn't work correctly for me with partial.emlx files and attachments (emlxpart).

I discovered that attachments displayed as "binary" after mbox imported to Mail.app because headers for attachments in the wrong place, instead of be inserted at the beginning of each attachment they placed at the end.

Works as described with no fuss - and helped me to move over 10,000 emails, including 6,000 in one folder, from Apple Mail 2.03 to Thunderbird 1.5b2 with no errors apart from half a dozen corrupt emails which turned out to be corrupt in the original. Highly recommended.

Very cool indeed... I safely and efficiently converted over 1,000 ".elmx" files when I migrated to Thunderbird. It only hiccupped on 6 of them (~99.5% success!), and I later found out that those emails were corrupt and had actually been crashing Mail.app v2.0.

This little app really helped me out of a jam when I had to downgrade somebody from tiger. It managed to convert all except one mailbox perfectly.

Thanks go out to the developer.
