ваши сервера в свой лист на основании примерно следующего:
<cut here>
Your servers are sending delayed bounces/challenge response mails/out of
office mails or other robotic mails in response to forged spam.
Many or all of these bounces were received by our spamtraps.
Spamtraps are email addresses that do not exist and have never existed; they
do not send mail and they should never receive mail. Nearly 100% of the
spams and viruses now in circulation forge the "from" addresses and so these
bounce messages are going to email addresses which had nothing to do with
the original email.
This not only affects spamcop's traps & blacklist, but also normal users
everywhere - your systems are no doubt sending out large volumes of these
bounces to people unrelated to messagaes being bounced.
<end cut>
И их предложения потом:
<cut here>
1) If you are going to reject mail, do it during the smtp conversation
with your mail gateway rather than sending a delayed bounce after the
message has already been queued.
2) If you must send delayed bounces or other robotic replies, do it from a
sacrificial lamb system, so that we may block it without blocking all your
more-legitimate mail.
3) Instead of sending bounces for invalid users, create a catch-all
account where mis-addressed mail lands. Assign a human being to sort
through that junk and decide what to do with it. I garantee 99% of it is
not worth bouncing. If you find accounts you do want to bounce, then do
it at the gateway.
<end cut>
Hаверняка кто-то уже наступал на такие грабли - просто не хочется
велосипед в очередной раз изобретать.
