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. -- Best regards, Paul. England, EU. Centos, Exim, Apache, Libre Office are the future. Micro$oft is the past. -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
