postoffice migration question

[Kelly Prescott]

We recently purchased an ISP running postoffice on NT from software.com...
Does any one know an easy way to migrate from it to the qmail Maildir
format?
Also, does any one have any idea of how to get the passwords out of the
program?
Sorry in advance if this is a little off topic, but as this is qmail we
are migrating to, I just thought some one might have had experience doing
it...
Thanks in advance.
