Fair enough - if it works for you on the particular mix of mail you
receive then carry on using it. I'm sure that plenty of people on this
list have special rules tailored to their own circumstances - the
flexibility Exim provides is why many of us are using it.
For our mail here such a rule would not be appropriate. I can't tell you
how many non-spam emails we receive without those headers because it isn't
something I monitor but I can certainly say that I've seen emails
without To: headers that users wished to receive (and I'm not just
referring to the exim list).
Mails without Date: and/or Message-ID: get flagged here and SpamAssassin
points added so, depending on the rest of the message, may get rejected
with an overthreshold spam score but those criteria on their own do not
reject.
Your parallel thread about rejecting messages with adsl in the reverse DNS
provides a similar point. It works for you (once the false matches are
sorted out). However there appear to be enough small businesses,
independent consultants etc., with whom our users wish to communicate,
whose mail comes from these sorts of IP addresses, for it to be
inappropriate here.
