We are planning on moving a large amount of Exchange mailboxes to UNIX mbox format.

My question is, does anyone know of any projects out there or of any tools that can assist in this conversion?

I've never liked mbox, but if that's what you want then I believe regular old 'fetchmail' can do it.

Maildir is a more flexible mailbox format IMHO.

if you decide to go the imap copy route, there is a utility to do this in the uw imap package, i think it's mailutil.

i can echo the others' concerns about using mbox format. There are lots of holy wars about what mailbox format is best on unix, but pretty much all the warriors agree that mbox is horrendous.

If you're using an imap server, choose a mailbox format that works well with that server.

If you use UW i'd probably get the latest imapd from uw and go with mix format; it has been in pretty wide use for the better part of a year and from the traffic on the imap list it sounds stable. Note that to deliver into mix (or mbx, UW's older non-mbox format), you need to use the dmail program that comes with uw. also note that unfortunately it defaults to mbox if you just tell it to deliver mail to an uncreated folder, you have to make the folder first with mailutil.

If you use cyrus, i guess it likes maildir format. Dovecot sounds like a reasonable choice and it can also use maildir.

Thanks Josh

Many ways:

1. write vbscript via CDO
2. write delphi/.net/... app via CDO
3. imap client copy
4. exmerge -> pst -> parse pst

...

One thing to point out... some ways end with TNEF attachements... I would go to maildir anyway.
