aHA! that's exactly what i was looking for... thanks!

now, i've read the docs re: that function, and added a filter_recipient
subroutine in my filter, but it doesn't appear to be doing anything.
i used the one from the example in the manpage, since that's basically all i
need it to do (replacing the hostnames with the appropriate ones) but it
doesn't appear to be getting called.  do i need to call it myself from some
other part of the filter? the man page wasn't all that clear about it.

are there any specific sendmail configuration settings i need to have in
place for this to work also?

currently i have 

define(`confSMART_HOST',`name.of.primary.mx.server')
FEATURE(`relay_entire_domain')

set in my sendmail.mc file, and in my mailertable:

mydomain    smtp:[name.of.primary.mx.server]


although i'm not sure if this is the correct way to have this machine
configured or not, really.
