[vchkpw] Migrating to a new machine question?

[Jesus Ruiz]

Hi, i have to migrate my qmail (qmail + vpopmail 5.2.1 +spamcontrol2.0.9) 
box to a new linux machine.

The problem is that my clients don't want to lose the email they save in 
the old server. When we change they account to the new server.

Any suggestion?

Thanks in advance
