That may be the killer problem right there. Is there any way to add an
alias to the database without having to rebuild the whole thing? Email
addresses are going to be added to this system on a regular basis and
the new addresses need to be available immediately.

I'm thinking that using LDAP aliases might be a better idea for this. Where
can I find a good How-to for setting up an LDAP directory to work with
Courier?
