Pop / Imap Usernames changed by server migration

Hi,

During the recent imgration of several servers your migration software has altered all the names of the login's of the server from userid to userid.domain

This plays havock with my users who cannot login now.

At first I thought it was related only to IMAP login's but now also seems to hit most POP3 accounts as well.

Is there A way to "update" the loginnames of these accounts somewhere ? I cannot seem to do it via Edit User.
