www4mail at szs.net will not respond to surnet.ru addresses

Hello accmailers ...

Requests from surnet.ru email addresses have been
causing us some difficulties recently. Typically,
numerous large binary files have been rejected at the
SMTP stage and bounced back to us, resulting in an
unnecessary load on our server.

Starting now, www4mail at szs.net will not respond to
requests from surnet.ru email addresses.

We regret the inconvenience to our surnet.ru users, but
it is also important that we manage the server
effectively, to ensure continued use by as many people
as possible.

Here is the list of mail servers that do not play nice
with www4mail`at`szs.net -

* All Yahoo servers
* com.sa
* maul.ru
* post.su
* surnet.ru

Other mail servers currently failing, but still accepted
by www4mail`at`szs.net -
* isac.gov.in
* sws.co.jp
* upr.edu.cu
