I hope it was not working on majordomo that caused this! :-)

How about using DB-style databases, but the additional information would 
be stored separated by '|'s

$user{'luser1@luser.com'} = "fullname|digests|var3|var4|varN|";

or is this similar to "MLDBM"? (not familiar with it)

One could have secondary indexes to speed some lookups, but 
synchronization and locking between 2+ dbm files becomes a tricky.
