Many people find this website after they receive a bounced email telling them
that their original email was rejected and to please visit the
Anonymous Postmasters Early Warning System (APEWS) at
If you bothered coming to this page, you are probably an innocent email user
who's email has bounced. Other people are referred to this website by friends
or search engines. However you found us, bear in mind that if any network
has rejected your email or other connections based on the APEWS list, it has
deliberately chosen to do so.
We do not control the network traffic on anyone else's servers; therefore, we
are not the ones rejecting your email, the mailserver you attempted to send
email to generated the bounce. We simply provide a public list of ranges of
Internet space (IP addresses) and domains which we do not wish to exchange traffic with.
Other networks may choose to filter traffic on their systems using our
list. APEWS never touches any email (or other data packets) between your
network and someone else's network. Any email bouncing or packet blocking
that takes place occurs at the receiving system.
Please understand our list is based on IP addresses and domain names only, not
email addresses, URLs, email software, message contents, or anything else.
We know that, as a user of the Internet, email and other connectivity is
important to you. We also know that unsolicited bulk email (spam) is bad.
We encourage you to ask your Internet Service Provider (ISP) to fix the
problem which has resulted in your mail bouncing or whatever other effects
of being listed in APEWS you may be experiencing. This is in the best
interest of all parties on the internet - except the people sending or
profiting from spam. Also be aware that having an email bounced does not
mean it must be spam, it just means your or your ISP's mailserver was
listed due to a spam related problem.
The first step in fixing the problem is to determine if the IP address your
email system uses to send mail is in the APEWS list. There is a lookup form
which will help you find out at the top of this page. If you were sent here
via a link in a bounced email, there should be a APEWS record number already
in the form's
lookup box. All you need to do is click on [TEST].
If your system is in the APEWS list, you should see a page with the reason(s)
listed this part of the Internet. If the form cannot find the corresponding
record, then it is not in the APEWS list. It may be that the IP address of
your mailserver is in some other blocklist and the place you were sending
email to incorrectly sent you here. There is also a chance that between the
time of your email bouncing and your coming here, the spam problem was corrected
and your email system is no longer listed in APEWS. There can be up to a eight
(8) hour time lag in the de-listing process.
If the lookup showed that the IP address is in APEWS, it is in a range of
addresses that are either a spam source, or a spam support service (e.g., a
webserver or nameserver). We normally publish the nature of the
problem on the page that is displayed when one does a lookup. This is sometimes
in the form of an evidence file. The evidence file will explain the problem. From
there, actions to fix the problem will consist of reporting the information on the page.
Only administrators responsible for the listed address(es) will have the authority
to fix the problem. Reading the
APEWS FAQ (Frequently Asked Questions) should
be of help in this. Be aware that some networks filter all IP traffic, not just email,
based on the APEWS list.
In other words, if you are not the administrator of the IP address(es) in
the APEWS list, then you should contact your ISP in order to attempt to resolve
the problem. When you contact your ISP, they will need a copy of the bounce
message which you received and/or other evidence of the problem. Be sure to
include the IP address which was rejected. Let them know that it is on the APEWS list and give them the URL of the lookup form.
Finally, most places listed in APEWS have shown a consistent pattern of
spamming, giving support to spammers, or tolerating spammers on their systems.
For this reason it may be difficult to get the administrators to provide a
solution. You may, in the end, need another method of sending email to the
growing list of networks and ISPs that use APEWS.
