[vchkpw] roaming user for imap

[dkwok]

I am sorry the question may be off topic.

I am running vpopmail and courier-imap, roaming with vpopmail works fine but for user using imap roaming does not work. I have searched any relevant info on this topic but it is rather scare. Would anyone point me to the right direction?

Many thanks in advance.
