Are there any legitimate cases where "to:" might be missing?
RFC 5322 says: "The only required header fields are the origination
date field and the originator address field(s).", i. e. the "Date:"
and the "From:" header field.
<https://datatracker.ietf.org/doc/html/rfc5322#section-3.6>
I have sent this answer without any address in the to header field.
The header doesn't look odd because the mailing list provides a TO
field. I'm fine if you want to send me an email without a TO field. I'd
like to look at the header.
I've just sent you an e-mail with no "To:" header.
Cheers.
