I'm honestly trying to figure out whether any mail systems treat mail
from sub.foo.com as being from foo.com when they make decisions about
sorting, filtering, and so forth. That's why I'd really appreciate
some actual examples if there are any. I'm not trying to be
confrontational here, I'm trying to gather data.
Some senders use email.example.com and example.com. If you want a
different treatment for filtering, you'll have to know beforehand
which subdomains to expect. It's different if the sender was an ISP
as host1.adsl.example.net is not treated the same as example.com then.
