That's their decision. If it was my company they would use a 'proper'
mailing application, integrated with a database, rather than a M$
make-do. That way every single email would be personally addressed to
the recipient.

Our Exim servers now accept no 'To:' headers but only for this list's
emails. Otherwise if senders can't be bothered to send us 'proper'
emails containing the basic 5 header fields:
From:
To:
Date:
Subject:
Message-ID:
their emails are refused. Providing the headers are present, the
content is not tested.
I can send emails without Message-IDs, Dates, Subjects, Froms and Tos
headers using an own coded programme (or script) but I don't.
I'm simple, 5 headers or the email is ignored.

Paul.
