I don't think that this is what I'm looking for, but I could be wrong.
Could you explain what you had in mind?

Well, the scenarios I stated are the ones I want to support. The most
common scenario is a customer email (user1@twentyten.org) comes in and that
email must be sent to the proper SMTP server. This is done very easily
using MySQL transport maps.

It hasn't been that easy to integrate the other scenarios. Sometimes the
email that comes in is an alias to another address and THAT address has the
transport map. Sometimes the email that comes in just needs to be forwarded
to another address (e.g. userx@hotmail.com).

How should I set it up so that everything is done in the right order?
Example:

- Email comes in for user2@twentyten.org
- transport map is checked -- user has no transport map
- user table is checked. user2@twentyten.org maps to user1@twentyten.org
- user1@twentyten.org should be sent to europe7.twentyten.org:2525
- mail is delivered

It would also work if aliases were always checked first, then transport...
Like I said, I can do each step of this individually, but I'm having trouble
getting the whole thing to work (i.e, having the aliases get looked up
properly and then having the transport maps looked up properly).
