the local users (myself, my wife, a friend) can authenticate EITHER as <username> or <username>@lerctr.org <http://lerctr.org>.
switching to all virtual users is NOT going to happen.
If I login to roundcube with <user>@lerctr.org <http://lerctr.org> it finds the autoindexed mail.
So, if I make everyone always authenticate as <user>@lerctr.org <http://lerctr.org> we should be fine.
and change my script to do doveadm -u <user>@<domain> instead of depending on the local user running the cron job.
question: Is there some way to have dovecot change what it sees to be <user>@lerctr.org <http://lerctr.org> when they login as <user>?
Dovecot is very configurable, but it can also take some time, effort and testing to get the configuration you want. Personally I don't mix user types since it takes out an element of complexity.
For your case you might find it useful to look into auth_default_realm
that can specify a domain name when one is not supplied.

Other things that might be useful: there is a method for returning a "user" field from the userdb query or passdb query which will change the username. Or there is another setting that can overriding values of fields returned by the userdb.

Hope it helps!
