[vchkpw] Migrating users from debian ipop to vpopmail with mysql.

[David Petruzzella]

I have a box that is being decommissioned running debian with ipop and I need to migrate the e-mail from that server to the new server which is running qmail, vpopmail, courier-imap, with mysql authentication and I was wondering what is the easiest way of doing it with out loosing any e-mail which is the most important thing.  If anyone has any suggestions, recommendations it will be greatly appreciated.  Thanks.
