[Dovecot] Rewriting username at login
I am trying to make a switch from Cyrus to Dovecot which has some historical accidents to it that I have to deal with and ideally would like to get rid of. One of them is that about half of the existing accounts have a different format for their login. All the newer accounts have their email address as login, the old ones use a dot instead of an at: - new: us...@domain.tld - old: user2.domain.tld I would like to migrate away from the all-dots notation since it leads to a lot of support questions, and for that I'd like to run in a compatibility-mode for a few months. Effectively, I want to get rid of all the old users and convert them all to the new scheme, and have the username rewritten at login, so every second to last dot gets rewritten to an at. This would ensure that we have no complaints and allow our users to migrate slowly. All users are currently stored in a MySQL database for Cyrus, but this will be changed to a Dovecot-LDAP combination. Is this possible? How could I achieve this? Kind regards, Gerry.

Is this possible? How could I achieve this? Check out the userdb section of the Wiki http://wiki.dovecot.org/UserDatabase, you can return a new uid. So make sure both spelling variants match the same entry (both for passdb and userdb) and override uid in userdb.
