IP Addresses that are listed by the SpamCop Blocking List are normally delisted 48 hours after the last spam report is processed.

The following text by Merlyn has helped others to understand the process in the past. Please also see "How can I get removed from SpamCop's blocking system?" at and John's explanation at

Lets go through this step by step together. Please read this carefully and
do not just scan it otherwise you will not understand the process.

1.) If you did not post the entire message you received about your email
being blocked it will be very hard to help you solve your problem.

2.) Next we will talk about why Spamcop cannot block your email.

Spamcop has no access to your email. When you send your email it goes
through your ISP's email server and travels through the Internet until it
reaches the ISP's server of the person you are sending your mail to then
their ISP's server routes it to their mailbox. Spamcop has no access to
either server or to the process between servers.

3.) Next we will discuss why you think Spamcop blocked you email.

You probably received a "bounced" email saying something like:

451 Blocked - see


email from blocked,refused by Spamcop,see


Anything saying your email was "blocked" by Spamcop and they directed you to
some page on the Spamcop site.

4.) Now we will talk about who is "really" blocking your email

Remember how we discussed the way your email traveled from your computer to
the recipients computer in #2? The only person who could block your email
is the recipients ISP or the recipient themselves. Most likely the
recipients ISP is using the Spamcop List (we will discuss this in the next
part #5) and they have blocked this email because the sending ISP's server
is a known source of spam on the Internet. You should be complaining to
your ISP because they allow spammers to use their resources which in turn
caused your email to get blocked. You ISP did receive complaints. You could
also contact the recipients ISP asking them to "whitelist" you. They
recipients ISP decided on their own to incorporate this list into their
email server software. Now you say you do not send spam but before you get
upset, read the next part about how this list is compiled by Spamcop.

5.) What is the Spamcop List and why do ISP's use it?

Spamcop runs a service for reporting spam. This is a free service where
people either send their spam email or copy their spam email in a form that
parses the email to find out where it originated from. Once the amount of
spam reaches a calculated amount the originating server is placed on the
list of spammers. This list is made freely available to anyone running an
email server to use to enable them to block email originating from known
spam servers.

This list only contains IP numbers and not email addresses as email
addresses in the "From" field can be readily forged and are not reliable.
The only reliable source is the IP address the spam originated from.

for more detailed information on how Spamcop works see:

6.) Final Notes (VERY IMPORTANT)

Before you start getting upset just remember what brought you here. Your
email was blocked, not by Spamcop but the ISP of the person you were sending
your email to. Spamcop has no control over what they do with their servers.
Also, get proactive and help stop the flow of spam. Complain to your ISP
because it is their servers that are being blocked. Let them know that you
are paying for email service in your contract with them and they are not
able to provide you with this service because they allow spammers to abuse
their servers.

I think you would agree with me that everyone is tired of receiving mortgage
quotes, penis enlargement, breast enhancement, weight loss, nude 40 year old
teenage sluts, Viagra, vacation, lottery, prescription drug, business
opportunities, genealogical, university degrees, gambling, get rich quick,
MLM, pyramid schemes, Web Cams, Russian brides, work from home, stock scams,
pirated software and everything else that is force fed into our inboxes.

If you have any more questions please post them here, there are many people
willing to assist. And remember most people in this group are here to help
you and they did not block your email so do not take your wrath out on them.
