We did this with Sendmail and {I forget what pop3d served as the
base} a year or so ago.  I modified the pop3d to use Sendmail's
BDB virtusertable, and it works great.

Not sure how comfortable you are with C, but it only took me a
few hours to implement -- examining source, sorting out BDB
versions, and adding the hack.  It's been some time since I've
messed with Qmail (Postfix is my poison of choice), and I'm not
familiar with your pop3d, but it shouldn't be too hard.

I need to migrate our mail to Postfix, so I'll be hacking up a
maildir-capable pop3d in the hopefully-not-too-distant future.

I like the trapdoor idea.  Adding a table of deprecated
usernames should do the trick.

Yep.  We map <someone@mycompany.tld> to "mycomp_someone" behind
the scenes.  Would be nice to eliminate the intermediate step and
go directly to uids, but I've been too lazy^H^H^H^Hbusy to mess
with libc, LDAP, or anything like that.
