Glad to hear you're concerned :).

Well, as long as you have their usernames and passwords, all you'd need to do 
it block off an hour or so, and recreate them under your Linux system. An 
SQL-based authentication backend would be ideal, but will take more time. If 
in a hurry, system users would be a good start.

You could check which opensource webmail servers support XML-based address 
formats, and simply import the data. SquirrelMail has been quite innovative 
over the years, but haven't used it much recently.

Forgive my ignorance with MDaemon mail storage, but sounds a lot like Maildir, 
or the early days of Eudora. At any rate, going Maildir on Linux would be the 
way to go (mbox has way too many issues).

I have setup many a SuSE box with this - using SuSE Linux 9.1 Professional (or 
later), using Exim as MTA and Courier as POP3/IMAP server (SuSE now comes 
with Courier on the CD's, so much much less hassle when installing it).

Just configure your Exim to handle mail for your domain, as normal. Then tell 
it to deliver mail using the Maildir format, under the local_delivery 
transport like so:

local_delivery:
  driver = appendfile
  directory = $home/Maildir
  maildir_format
  delivery_date_add
  envelope_to_add
  return_path_add

And that's it. You don't have to create a Maildir directory under each users 
homedir, Exim will create it when delivering the first e-mail, in case it 
doesn't exist.

Simply install Courier-IMAP from the CD's (if SuSE), install a webmail server 
(I like Squirrel), and you're good to go. I think SuSE also have SquirrelMail 
on the CD's.

ClamAV is free.
