I'd like to hear a valid reason you actually want these messages. And a

Since it breaks legitimate mail, I'll probably not implement something that blocks empty messages.

        I have seen where empty messages are used for replies to listmail
managers (no body required, just a response), and other types of
"automated" mail. Frankly, I often send a short message using only the
Subject.

(Note: I haven't fully read the entire thread, so my explanation
may not apply. For example, I do require non-blank Subject lines, so if
the discussion applies to headers, also, then things are a bit different.)

The discussion was about rejecting the following SMTP session:

HELO domain.com
MAIL FROM:<[EMAIL PROTECTED]>
RCPT TO:<[EMAIL PROTECTED]>
DATA
.
QUIT

i.e. nothing in the DATA section whatsoever. This isn't "legitimate mail" in any sense whatsoever (since there's no mail there, only an envelope). It's completely illegitimate. It violates RFC 2822. It communicates nothing.

Matt.
