We're going to do something like this to route mail from our smtp
gateways to our new Cyrus server.  But it loses +detail, unless
you make TWO entries for each user, the second entry being

someuser+*@mydomain.com  %1%3 at smtp-server.mydomain.com

(it might be %1%2 there, I forget).  I don't like making two entries
so I think we will make a custom table and a few lines of rules in
SLocal_localaddr (local hacks for ruleset 5) to check that table
with or without +detail.  Sort of the same thing really.



But the point as to Mimedefang-- right, you need sendmail on the
gateway able to identify which addresses are valid, so that any
others can be rejected at the gateway.
