There is, to my knowledge, no magic silver bullet to do this - you will
have to code your filter rules file to parse out the recipient domain and
query the appropriate downstream smtp server. If there are only a few
static ones, just code a few "if" statements in filter_recipient() like
these:
if ($recipient =~ /[EMAIL PROTECTED]>?/i) {
return md_check_against_smtp_server($sender, $recipient,
"smtp-in.foo.com", "sales.foo.com")
}
if ($recipient =~ /[EMAIL PROTECTED]>?/i) {
return md_check_against_smtp_server($sender, $recipient,
"smtp-in.foo.com", "engineering.foo.com")
}
Note that if Engineering or Sales changes their mail host name, you will
have to change your filter appropriately. If you have a lot of MX's, you
will need a more flexible (translation: elaborate) checking scheme in
filter_recipient().
