That would require the calling applications to know to do a lookup on redirect.somedomain.com and not somedomain.com. SpamAssassin for one won't do that.
Actually I thought SpamAssassin did check two level domains like foo.com on two and three levels. Not sure if it still does that but I recall it doing that at oue point, i.e. both redirect.somedomain.com *and* somedomain.com. were checked.
Pretty sure we saw that in the DNS traffic SA was generating, or showing up in debug mode. But maybe the domain handling's been updated to be more specific since then.
Hmm, I could be mistaken. I guess I could check the code or a debug, but are there any three level domains listed to do a quick check against?
SA also checks all visible hosts (including redirected-to ones) in a URI, including all of a redirector, so:
http://redirector.clubie.isp/blah/feh/http://spammer.com/
and similiar style URIs are checked by spamassassin for at least clubie.isp and spammer.com. That's what I recall from the original SA development of redirector handling.
Yeah, it'll lookup both those domains. Any time it finds http(s) in the URI it assumes that it and the rest is a domain being redirected to.
