[r-t] Messages apparently rejected as s p a m

[Admin]

Some list members have received messages like this:

______________________________________________________

ATTENTION!

A message you recently sent to a 0Spam.com user with the subject "..."
was not delivered because they are using the 0Spam.com anti-spam
service. Please click the link below to confirm that this is not spam.
When you confirm, this message and all future messages you send will
automatically be accepted.

______________________________________________________

||||Please note that these messages do not come from the list itself.||||

What is happening is this. At least one subscriber is using 0Spam.com.
This rejects messages from unrecognised sources and sends a challenge
like the one above to the sender of the message.

There are reasons not to welcome this practice: see
http://www.jgc.org/antispam/02282005-60dfea1d4f36a4071c21d1ba86f5e988.pdf

You may wish not to accept the invitation to click on the link for the
reasons given there.

If you are using 0Spam, please make absolutely sure that you have set
it to accept messages from this list.  List messages have in their
subject header
[c-r] for change-ringers
[r-c] for ringing-chat
[m-r] for mini-ringerz
[r-t] for ringing-theory
and you can set 0Spam accordingly.

Better still, use some other form of spam-filter.
