"The DSBL
lists contain the IP addresses of servers which have relayed
special test messages to listme@listme.dsbl.org; this can
happen if the server is an open relay, an open proxy or has
another vulnerability that allows anybody to deliver email to
anywhere, through that server." |
|
| |
|
|
| |
Note: SEER
does not use the unconfirmed or multihop lists at dsbl.org. If
your host is listed in either of these lists and not in
list.dsbl.org then it was not a dsbl listing which caused your
bounce. |

This list includes among others the SPEWS and Spamhaus
lists described below. |
|
| |
|
|
|
|
It also lists open relays and other spam sources. If
your mail server has been listed in other lists, it may also
be listed here. Please review the documentation at this site
carefully. |

|
| SPEWS |
"SPEWS is a list of areas on the Internet which several
system administrators, ISP postmasters, and other service
providers have assembled and use to deny email and in some
cases, all network traffic from." |

"The SBL

|
| bl.spamcop.net |
A dynamic
list of actual spam sources. IP addresses are listed as soon
as spam starts and automatically delisted shortly after spam
stops. |
Just
wait. When the spam stops, so will the listing. |
| |
|
|
| |
(Do note,
however, that many hosts seem to pop in and out of the Spamcop
block list regularly and hosts will stay listed there from a
few hours to a few days at a time. If this is a problem for
you, please complain to your Internet Service
Provider.) |

We
also use a small number of lists which list entire networks or
countries. We only block mail from networks or countries which
have sent us significant amounts of spam and we only block
mail from countries where we have no trading relationships and
from where we would expect no business email. |
| |
| And finally... |
|
Your mail host may be listed in more than one block
list. We blocked your mail using the first listing we found
among the lists named above. You should check to see where
else your server is listed if you are cleaning up after an
open relay incident.
For a comprehensive view of where your mail server is
listed in a block list, try visiting OpenRBL.org and
entering your server's IP
there. |
