Thank you for writing to the MAPS Dynamic User List (DUL) Maintainers.
This email address is used to submit DUL listing requests, DUL removal
requests, and for other communication regarding the MAPS DUL.
The MAPS DUL is a list of known dynamic (including dial-up) end user
networks, and listings appear either due to junk e-mail complaints by
DUL subscribers or by the Internet provider's request. It is NOT a list
of insecure or open relay mail servers, nor is it a list of networks we
consider friendly or neutral to spammers. If you are blocked by a
DUL subscriber, they are not saying you are a spammer nor are they
saying your Internet provider is a spam problem.
[SPECIFIC ISP NOTES and END USER INFORMATION] (Read before proceeding)
Specific Internet providers may have special notes for their users being
blocked by DUL subscribers. You may read these notes on the End User
Information page:
[REMOVALS]
If you want us to remove listings of former dynamic ranges or other
incorrect listings, we need to know the IP addresses listed. If you
already provided these to us, we will remove them once we verified
they are not used for dynamic end users, and you will receive
e-mail confirming their removal.
If you are asking us to remove a listing for a network range that is still
for dynamic end users, note that we will only remove such listings at
the request of the network's admins. We will not honor remove requests
from end users of a network. Contact your admins and ask them to write us.
NOTE: A removal may take some time to propagate out to subscribers.
[ISP PARTICIPATION AND "BLACKHOLING"]
If you are an Internet provider concerned with your dynamic end user
ranges appearing in the MAPS DUL, please remember that the DUL is not
a spam source list. Many Internet providers willingly provide listings for
us so they can enforce their terms of service more effectively. You can
reduce dynamic IP spam incidents from your network by working with us.
[MAIL SERVERS ON END USER IP]
If you operate a mail server or relay on an end user IP listed in the DUL,
you can send mail to DUL subscribers by directing it through your
Internet provider's outgoing servers, just as you would with a mail client.
Please see the DUL Gateways page for configuration examples:

第二封是这样的
60.190.102.× is listed on our Dynamic User List (DUL) because
it appears to be an address which is dynamically-assigned.
This does not imply that you are a spammer, though a great
deal of spam comes from zombied computers using similar
addresses. Further details may be found at
Since neither DNS nor whois information indicates any association
between you and this address we need to hear from an authorized
representative of your ISP before considering any removal of
the listing.
If this is a dynamic address, please contact your ISP for help
in configuring your computer to relay mail through their mail
server, or see
