	Why do I get the message 550 IP in XBL SBL PBL or SCBL when sending mail

Solution If you receive either of the 4 messages above when trying to send email, it would appear that someone has labelled the IP address of the machine you are using to connect to the internet with as a source of spam.

To find out why this has happened as well as how to get unblocked you will first need to visit a site such as www.whatsmyip.net or www.whatsmyip.org

This will tell you your IP address, it will be of the form:

XX.XX.XX.XX

If you are receiving either:
550 IP in XBL,
550 IP in SBL, or
550 IP in PBL,

please go to http://www.spamhaus.org/xbl/index.lasso and enter your IP address into the form.

If you receive the 550 IP in SCBL message then please go to http://www.spamcop.net/bl.shtml and enter your IP address.

Both of these pages will explain the reason for the black listing and they also have a "remove IP address" facility. Please note that it may take several hours for your IP address to become delisted.
