I don't know about the original poster but the ISP I work for has been
doing e-mail with sendmail and IMAP-UW.
All usernames are of the form username@maindomain, only they don't use
@maindomain.
Customer domain users use mailboxes of the form
domainSpecificPrefixOf2or3characters_localpart for
localpart@customerdomain.
virtusertable:
localpart@xxxxxxxxxxxxxxxxxx cd_localpart
We would like to get those users out of the maindomain and have them
switch to using mailboxes of localpart@xxxxxxxxxxxxxxxxxx and be able
to login as localpart@xxxxxxxxxxxxxxxxxx but have compatibility with
the old way of loging in as cd_localpart as well, at least during the
transition period.
But we haven't gotten to giving that a lot of thought yet.
