This change is of a particularly technical nature and only applies to a
small select number of Demon customers. Most of our users, particularly
standard dial up customers, will not be affected by this change. 

As part of this work it will be necessary to change machines and / or
IP addresses.

We are aware that a number of users access our mail system through
'fire-walls' and other security systems.

We are therefore setting aside a block of IP addresses as a 'trusted'
mail network from which all mail will originate. No other machines
will be installed on this network. Customers that operate 'fire-walls'
or other security systems that rely on knowing the IP address of the
mail machines should therefore arrange for this subnet to be allowed
access to their machines.

The new subnet is 194.217.0.0/28 and changes should be made as soon as
possible. You should trust any machine on this network.

[194.217.0.0/28 means the 16 addresses from 194.217.0.0 to
194.217.0.15 inclusive]

Whilst the work to bring this new subnet and associated machines into
service is carried out, the existing machines will still continue to
deliver mail. You should continue to allow the current machines to
deliver mail to you. We will make an appropriate annoucement when
only machines on the new subnet will deliver mail.

Most of our users, particularly standard dial up customers, will not
be affected by this change. If you do not understand the above, you
should not be concerned as it will not affect you.
