Importing the Selected Messages as Message Files
If you’re using the 64-bit version of MailMate, there is a built-in bundle for importing from EagleFiler. First, go to the Bundles tab of MailMate’s preferences window and make sure that EagleFiler is checked. Then you can select messages in MailMate and choose Command ‣ EagleFiler ‣ Add to import them into EagleFiler.
Importing the Selected Messages as Mailbox Files
Recent versions of MailMate include a bundle that adds the Command ‣ Export command, which exports the messages in mbox format. You can then import the mbox into EagleFiler. This is the most efficient way of importing from MailMate.
Manually Importing Message Files
You can import individual messages from MailMate by dragging and dropping them.
To import a whole mailbox, find its folder in the folder:
/Users/<username>/Library/Application Support/MailMate/Messages/IMAP/
and drag it into EagleFiler. EagleFiler will import all the .eml files and skip the .emlh files.
