Changes to Mail Relays
Malcolm S. Muir
This announcement will not affect you if you use Dial Up, Home
Broadband, HomeOffice Broadband or any other Demon product where
email is collected by POP3.
We will be making some changes to the mail relays commencing:
Friday 8th June 2007
Starting on the above date we will be commencing on a programme
to replace the mail relay servers which form the backup MX hosts
for customers who have domains hosted with us.
These servers are intended to accept and relay email to hosting
customers when their own mail servers are unavailable, they are
not provided as a primary mail server.
Whilst the new mail relays will provide similar function to the
servers they replace, there will be some significant changes:
They will not act as a primary MX, as customers are required to
provide their own mail servers.
Compliance with RFC 2821 will be enforced. Details of RFC 2821
can be found at:
<ftp://ftp.demon.co.uk/pub/mirrors/internic/rfc/rfc2821.txt>
Mail will be rejected if the sending IP Address is listed in
selected blacklists, initially by using Zen:
Mail will be rejected from non-existent domains, or invalid IP
addresses.
We will implement Greylisting.
We will implement Recipient Address Verification such that if
the primary MX would refuse a mail, so will the relays.
