how is this done?

Thanks, Bill

You have to use the messages stored in the '~/Library/Mail' folder. Select the right folder, and use the 'Messages' folder right inside.

I have 20 email inboxes that I monitor. I have not been able to get the dredge to work at all. I have tried /mailboxname/Messages, the mailbox name alone and several other combinations but I just can't get it to work.

Can you let me know how to get the dredge to work in my environment?

Thanks!

'/mailboxname/Messages' is correct and works fine here. Check if the 'Messages' folder is not empty (some are) and that you are using very last version.

In the Library folder I don't see more than /Mail/AccountTypes/com.apple.builtin.mailaccounts/MailAccount.plist

How can I extract files from Apple Mail with eMail Extractor

(I used Entourage before and there the extraction was easy)

found it

maybe this will help someone:

Archive the Mailbox (right click + "Archive Mailbox...") and drag/drop the file mbox into Extractor
