What file extension does emClient use? Need to import mbx files from Eudora

Hi, I’m happily using emClient and am now thinking to help a friend switch from Eudora to emClient. I saw in another post that mbx files don’t import smoothly. If I convert them to something else - what file extension does emClient use?

(E.g. if I converted them to Outlook - it would be converting them to pst files

Sounds like it is a POP3 account. If your friend doesn’t have a lot of emails, you could create a free @outlook.com or @gmail.com email account for him, set it up on Eudora as IMAP, copy/paste folders and messages to it, install eM Client, add the free account along with the regular one, and then copy/paste back to the original account.
