How to pass the local messages through a POP/IMAP server

Hi Geeks! Recently i was looking for a way to migrate the MAC mail2 users to Lotus notes mailing system. For this I will have to convert the mails from .mbox to .NSF format.

I was suggest that it could be done by passing the mails on the local machine to/through the Domino server.

Could you please suggest as to how this could be done.

Thanking you in advance
