The header that I am seeing is:
To: IETF-Announce: ;
Formally, that's a valid string in RFC822, no matter how obscure the
construct has become. It's the <group> construct.
Perhaps surprisingly, it was not deprecated in RFC2822.
And SpamAssassin marks a To line with only a comment as malformed. So it
considers:
To: (topic)
to be invalid. It was valid in RFC822 but is not valid in RFC2822.
