MataSpam (KillSpam) Services presents

Spam Blocked?

There has been an exponential increase in spam on the Internet in the recent past and many domains have had to put measures into place to keep the excessive spam from flooding users' email boxes.

MataSpam was launched in March 2006 to help Panamanian and Offshore Companies stem the tide of Spam (Unsolicited Commercial and also "Non-profit" e-Mail). We operate under Panamanian Laws and are therefore exempt from providing access to our users inboxes to so called "legal" spammers.

Unsolicited e-Mails cost our customers time, and money. They consume bandwidth and storage space. MataSpam is a first line of defense in the fight to reclaim your Inbox.

If you've been sent an error message telling you to visit this page it's because the domain you're trying to reach is using the Aggresive Anti Spam, Anti Viral services of MataSpam (KillSpam)to help prevent spam and malware from reaching users' email boxes.

Because checking for spam is not an exact science we may have accidentally blocked your email even though you're not sending spam.

If you're not using your ISP's email server to send your email then switching to that server is generally the best way to send email. Many ISPs block their customers' ability to send email from their own connections or through other email servers besides those the ISP supplies for that purpose.

To "whitelist" your email server, please send an email to notspam (at) mataspam.com

The Subject of the email should be "UNBLOCK REQUEST". Anything else will be thrown away and not seen by anyone.

The first line of the email body should be your return address.

The second line of the email body should be the email address you're trying to reach.

The rest of the e-mail should detail WHY we should unblock you and why you believe you are not a spammer. Please don't mention a website that might be listed on the SURBL database, or the message will be rejected as well.

We'll contact you if necessary and unblock you if possible.

If we can't unblock you (for example, if you ARE a spammer), we might write you back and let you know why. Then again, we might not.

How it works

Our Customer uses the MataSpam service to check several local and third-party "blocklists" to keep spam from reaching his or her mailboxes. Depending on the blocklist that blocked your email there are several steps you may wish to take to see why your email was blocked:

LBL or BSHL

If your message mentioned "LBL" or "BSHL" then your mailserver was blocked by conscious action of the server administrator. You should contact our "whitelist" address above to find out why you were blocked and what you can do to be unblocked.

ORDB

If your message mentioned "ORDB" you should read the FAQ at http://www.ordb.org/faq/ and check your sending IP address at http://www.ordb.org/lookup/ to see why your email may have been blocked.

(It may not be YOUR IP that is blocked, but the IP that your ISP uses to send mail.) ORDB is the Open Relay Database. This protects our mailserver from receiving email from servers that are running insecure open relays that are commonly abused by spammers.

Spamhaus

If your message mentioned "spamhaus" you should read the FAQ at http://www.spamhaus.org/sbl/sbl-faqs.lasso and check the site at http://www.spamhaus.org/ to see why your email may have been blocked.

SpamCop

If your message mentioned "spamcop" you should read the SpamCop site at http://www.spamcop.net/ and check your IP at http://spamcop.net/reported.shtml to see why your email may have been blocked.

SORBS

If your message mentioned "sorbs" you should read the SORBS site and check your IP at the SORBS website at http://www.dnsbl.sorbs.net to see why your email may have been blocked.

(It may not be your IP that is blocked, but the IP that your ISP uses to send email, or the IP may be an open relay.)

SURBL

If your message mentioned SURBL list, the content of the message you sent MENTIONS websites which are listed in the SURBL Spam URI Realtime Blocklists. Those sites usually promoted their products via spam. Visit http://www.surbl.org/ and remove the offending sites' URL from your emails.

Other blocks are put in place due to the number of open relays on DSL networks. If your domain name resolves to a DSL or ADSL domain or is a known dynamic block of IP addresses used by ISPs that should not be hosting a mail server (for example, dsl-verizon.net or *.da.uu.net) you should probably send email through your ISP's SMTP server instead of directly from your own home mail server. Or, contact your ISP about setting up proper reverse DNS so that your IP does not resolve to a DSL or dialup domain name.

NJABL

If your message mentioned "njabl" you should read the NJABL "end-user" information at http://www.njabl.org/enduser.html and the listings page at http://njabl.org/listing.html for information about how your IP address ended up in that blocklist.

CBL

If your message mentioned "cbl" you should check the CBL (Composite Blocking List) webiste information at http://cbl.abuseat.org/ and look up your IP at http://cbl.abuseat.org/lookup.cgi to see why your IP may have ended up in that blocklist.

OPM

If your message mentioned "OPM" you should read the OPM information at http://opm.blitzed.org/info for information about how your IP address ended up in that blocklist.

COMPLETE WHOIS

If your message mentioned "Complete Whois" you should read the Complete Whois site at http://www.completewhois.com to see why your email may have been blocked.

RFC IGNORANT

If your message mentioned "RFC Ignorant", your trouble lies with your Internet Service Provider who is not playing by the rules. Either convince them to follow RFC rules to send e-mail or switch to another provider. Visit http://www.rfc-ignorant.org.

Sample Error Message #1:

Sample Error Message #2:

The first sample above indicates your email was blocked by NJABL, and the second that your email was blocked by decision of the MataSpam administrator. Either way you can send an email to our whitelist address above to be unlisted, and in the case of the email blocked by NJABL, you could visit their website (see above) to determine why your email may have been blocked.
