One of the reason I use qmail pop3 is that it will do learn password and use Devocot for imap.

IIRC, this was intentional. It's impossible to learn a password via CRAM-MD5, so we fail until we can learn a password through some other method.

Password learning happens in vchkpw, but I guess it should move into vpopmail so any app calling the API can have a password "learned".

And to those who recommend Dovecot, it probably doesn't do learning either, for the same reasons.

I just checked courier 3.0.8, and it looks like it should update the password... I checked dovecot 1.0.10, and found this, "Thanks to Courier-IMAP for showing how the vpopmail API should be used". It doesn't appear to have code that updates the password.

Unfortunately, there's no way to update libvpopmail to have it learn the password. We'll have to update the individual apps (courier and dovecot) and get the maintainers to accept the changes into the next release.
