I am running spamassassin (if you have a public mail server you've got to
nowadays.) but postfix is rejecting the mail before it even gets to there,
at the RCPT stage.
One thing I noticed from the logs is the offending senders are
canonicalizing the CNAME. I.e. they are sending to
firstname.lastname@example.org rather than email@example.com .
The ones that don't do that can send just fine.
What I'm wondering is why they're doing that? Is there something I can do
on my end to make them not do that? I could change the CNAME to an A but
then what are CNAMEs good for?
Or are sites like yahoo just broken in this regard?
