It appears that Viktor Dukhovni via Exim-users <exim-users@???> said:

Huh, you're right. In my minor defense, the CNAME code was written in
1998, RFC 2821 was published in 2001, and as far as I can tell this is
the first time in 20 years that I've sent to a CNAME'd domain that
caused a problem. I'll go patch the code.

Just wondering, I'm pretty sure I sent mail to this list in the past.
Is the CNAME new?

R's,
John
