I'm having problems with cmuImport too, I it didn't update the file /etc/mail/virtusertable, so the users can't get any e-mail. I was moving from a raq3 to a raq4.I have had small problems like yours as well, I found that all I need to do is reset there password and everything works fine.
Yeah, CMU is a great tool, but it still has a bit to go regarding password migration... All your user's passwords might not get updated correctly during the transfer... From what I can tell, it seems to be users that have symbols <!@#$%^&*()> in their passwords that get hosed during the import.. But just copy the password <and JUST the password> portion of each user out of /etc/shadow file over to the new /etc/shadow file on the new machine..
It's also a really good idea <from what Duncan has said> to run Meta Verify after transfering users/domains between machines... It makes sure your backend is all fine and dandy...
