Using an email server on a dial-up, cable or DSL type connection:
If your an end user, your e-mail program should send it's outbound mail through your Internet Providers mail system first. Many spammers send junk email directly from dial-up, cable and DSL connections. In all
practicality there's no need for these types of systems to send email directly to our server. So we
compile listings of dial-up, cable and DSL address ranges, and add those to our lists. We also include any other address ranges that appear to be dynamically assigned as well.
-
I'm not a spammer, why is my server in your list?
When we notice a professional spammer, especially if spam comes from numerically similar IP addresses, we use methods to determine the range of IP addresses in question, and then add that entire address block to our list. If the
spammers IP addresses are part of a certain size block, we assume the spammer has been allocated the entire block. This may not always be the case, but we have no way of knowing this. If you're caught in this situation,
talk to your ISP about getting rid of their spammers.
-
Your using a server or ISP that sends spam.
If a server or Internet Provider is determined to be a spam source, that means we have received spam that originated from that system. If you want such a listing removed, please explain how the
spam came from/through that system and what has been done to prevent additional spam from transiting your system.
Frequently Asked Questions
-
Why wasn't I notified before my server was added to your list?
Our systems scan thousands of emails every day, automatically adding systems that meet our listing criteria, far too many to notify the owner of each and every one. Besides many thousands are home computers infected with Trojan
horse viruses that are sending spam without the owners knowledge.
-
My server is on a permanent cable or DSL connection, why is it listed?
If the DNS PTR record for the IP address of your mail server suggests a non-permanent connection, we may list it. Particularly if other systems with similar DNS PTR records suggest this, we list it.
It's possible you have a static IP address within a range of addresses that's otherwise largely dynamic or at least the PTR records suggest it is dynamic. If this is the case, let us know. If your PTR record suggests the IP is static we'll remove your IP from our list.
If you have a static IP address and the DNS PTR record looks just like the dynamic DNS PTR records and IP addresses around it,
you need to contact your ISP. Your ISP needs to setup their DNS system to correctly identify your server with the proper A, PTR and MX records.
This is a accepted Internet standard and requirement. If your provider is unwilling to perform
this service they
are lazy and we suggest you choose a "real" Internet Provider.
