Why was my email message to Gap Inc. rejected?
In an effort to reduce spam, Gap Inc. subscribes to MAPS, a leading spam blocking service. The
MAPS organization maintains lists of mail servers that exhibit configuration issues consistent with
those used by spammers. The specific configuration issue detected will determine which MAPS
block list a mail server is placed on.
The IP address of the mail server that your message came from is currently listed on one of the
MAPS block lists. That mail server might be owned by your organization, owned by your Internet
service provider, or might be a system that was previously compromised by malicious code and is
now being used without authorization.
How you address this problem will depend on who owns the mail server you are using and the
specific MAPS block list that the server is placed on. Some troubleshooting guidelines are offered
below, but for direct support on this issue, you, your local system or mail administrator, or your
Internet service provider should contact MAPS directly.
For more information about the MAPS organization, including contact information, please visit http://www.mail-abuse.com/index.html.
How do I determine the IP address of my mail server?
In order to identify which MAPS list your mail server is on, you will need the IP address of the mail
server in question. If you don’t know that IP address, you can refer to the message body of the
bounce message you received or analyze its message headers. Another way is to use nslookup.
Below is a Web-based nslookup tool and instructions for using it to find the IP address of your
domain’s mail server(s):
1. Go to the Web-based nslookup tool: http://www.zoneedit.com/lookup.html.
2. Under DNS Lookup, enter the following information in the appropriate fields:
• Item 1: Enter the domain name that you are sending mail from.
• Item 2: Select Mail Server (MX).
• Item 3: Leave this field blank.
• Item 4: Click on “Look it up.”
3. The tool will return all entries found in DNS.
If the mail server is running on a compromised host, you may need to determine the IP address of
your own machine. For more information, refer to the removal instructions for the DUL list below.
Otherwise, for additional support, please contact either your local system or mail administrator or
your Internet service provider as appropriate.
How do I determine which MAPS list my mail server is on?
You can use the MAPS Lookup Tool to determine if your mail server’s IP address is listed on any
of the MAPS lists. That tool is located at: http://www.mail-abuse.com/cgi-bin/lookup.
If your mail server’s IP address is found on any list, MAPS will provide the list name and the
specific entry on that list (e.g., a single IP address or a block of IP addresses).
Now that I know which MAPS list my mail server is on, how do I resolve the problem?
For suggestions on how to resolve this problem, refer to the appropriate MAPS list below. For
support on this issue, please contact MAPS directly. For more information about the MAPS
organization, including contact information, please visit: http://www.mail-abuse.com/index.html.
RBL: Realtime Blackhole List
RBL Overview
The RBL is a comprehensive list of IP addresses of known sources of unsolicited email. The list
includes IP addresses of sources that have been shown to send spam as well as those who
support the sending of spam (i.e. offering services to spammers or allowing their resources to be
used by those who send spam). For more information about the RBL, refer to: http://www.mail-abuse.com/services/mds_rbl.html.
Removing an IP Address from the MAPS RBL
Some of the reasons your IP address may be listed on the MAPS RBL are:
• Known spam source
• Multi-hop open relay
• Compromised host
• Insecure formmail script
• Provider of spam support services
To get your IP address removed from the MAPS RBL, you must contact the MAPS RBL team via
one of the following methods:
Email: rbl@mail-abuse.com
Phone: +1.408.453.6277 x1
To expedite your removal request, you should complete the following tasks or be prepared to
provide the following information to the MAPS RBL team:
• The IP address that you want removed from the list
• What you are doing to correct any of the issues identified above (if you don’t know what the
issue is, the MAPS RBL team will assist you)
• Your organization’s mail abuse handling policies
• Your organization’s acceptable use policies
DUL: Dynamic User List
DUL Overview
The DUL is a comprehensive list of IP addresses that should not be running mail servers, usually
dynamically assigned IP addresses. This is often due to a virus or other type of illegal or unknown
use of the end-user’s resources. Mass emailers often use compromised machines to directly
connect to the mail servers of their targets. The victim of the compromise is often unaware that
this illegal activity is taking place on his computer. This list blocks those addresses where spam
should not be sourced and helps to prevent the end-user from unknowingly supporting spam. For
more information about the DUL, refer to: http://www.mail-abuse.com/services/mds_dul.html.
Removing an IP Address from the MAPS DUL
Some of the reasons your IP address may be listed on the MAPS DUL are:
• The IP address is identified as a source of trespass spam, meaning that a “mail server” or
“spam engine” was set up on a dial-up line
• Spam victims report the IP address to MAPS
• The Internet service provider has voluntarily provided a list of all dial-up and dynamic IP
addresses to MAPS
To get your IP address removed from the MAPS DUL, you must contact the MAPS DUL team via
one of the following methods:
Email: dul@mail-abuse.com
Web form: http://www.mail-abuse.com/cgi-bin/nph-dul-remove
To expedite your removal request, you should complete the following tasks or be prepared to
provide the following information to the MAPS DUL team:
• The IP address you want removed from the list
• Network organization information. Providing MAPS with a list of your public dynamic and
static IP addresses is often the simplest way to address these issues
• Measures you have taken to prevent trespass spam
• Ensure that you have a reverse DNS entry setup for all of your public static IP addresses,
since the lack of one is indicative of a dynamic IP address
• Ensure that your mail servers accurately report the domain(s) for which they are accepting
mail
• Your organization’s mail abuse handling policies
• Your organization’s acceptable use policies
• If you are unsure of what the issue is, or feel that your IP address has been listed in error, the
MAPS DUL team will assist you
RSS: Relay Spam Stopper
RSS Overview
The RSS is an extensive list of IP addresses of known insecure mail servers. A third-party relay,
also known as an “open relay” or “insecure relay,” is a mail server that will route mail for any third
party to any other third party, no questions asked. Spammers take advantage of open relays in an
effort to cover their tracks. For more information about the RSS, refer to: http://www.mail-abuse.com/services/mds_rss.html.
Removing an IP Address from the MAPS RSS
The reason your IP address may be listed on the MAPS RSS is:
• The IP address is an “open relay” and has been utilized to send spam
To get your IP address removed from the MAPS RSS, you must contact the MAPS RSS team via
the following method:
Web form: http://rss.mail-abuse.com/cgi-bin/nph-rss-remove

provide the following information to the MAPS RSS team:
• The IP address that you want removed from the list
• Secure your mail server to prevent spam relaying by modifying your server preferences or
configuration file
OPS: Open Proxy Stopper
OPS Overview
The OPS is an extensive list of IP addresses that have been used as an open proxy to relay
spam. An open proxy is where any port, other than the SMTP port 25, on a machine is used to
route mail for a third party to another third party, no questions asked. Spammers take advantage
of open proxies and the victim of this compromise is often unaware that this illegal activity is
taking place on her computer. For more information about the OPS, refer to: http://www.mail-abuse.com/services/mds_ops.html.
Removing an IP Address from the MAPS OPS

NML: Non-Confirming Mailing List
NML Overview
The NML is an extensive list of IP addresses that are known sources of mailing lists that do not

mailing list. Only by having a fully verified opt-in process can one be certain that the person
signing up for the mailing list is, in fact, the person who rightfully controls the email address in
question. For more information about the NML, refer to: http://www.mail-abuse.com/services/mds_nml.html.
