Having posted to the list, one naturally awaits responses from the same
list.

I did get a message advising me of your email attempt:-

------------------------------
REJECTED

Sender's IP    : 78.32.30.217 => gw-1.arm.linux.org.uk => 78.32.30.217
Sender's HELO  : pandora.arm.linux.org.uk => 78.32.30.218
Sender's port  : 59491
Our server     : m2.u22.net
Date           : Monday, 20:46:32, 15 September 2014 (+01:00)
SMTP sender    :
SMTP recipient :
Message-ID     :
Location       : Petworth, West Sussex, United Kingdom


Report : [2B21] HOST <> HELO

------------------------------

With circa 120-200 spam attempts every day, although less at weekends, I
am rejecting everything including:-

* no host name
* no rDNS
* none resolving HELO/EHLO
* host names on the my spammers' list
* host names that appear to be home Internet connections

If people wish to email me, then have a HELO/EHLO that resolves to the
host name.

With wonderful Exim that is extremely simple to achieve. It could not be
easier. If I, then a complete Linux and Exim novice, can do that on the
first day I used Exim,. I am sure others can too.

If mail senders wish to use sloppily configured MTA, kindly avoid
blaming me for other people's sub-standard workmanship. It is quick and
easy to have properly resolving HELO names. I can make a change to an
Exim configuration file, then upload to it to 4 servers in 4 different
countries and restart all of them is less than 1 minute total time.
