My IP Has Been Blacklisted What Can I Do

May 17th, 2011

sypware, malware, key loggers, viruses I think my IP Addresses may have been ‘Blacklisted’

If you are trying to send email but emails are being bounced or not delivered to the recipients email system – your IP may have been blacklisted.

Your IP address can be ‘Blacklisted’ for a number of reasons

  • You have a virus or malware on your PC or network which is sending out SPAM
  • You have been reported for sending out SPAM
  • Your Mail server / Exchange server has been compromised

What can you do? Well the first thing is to make sure that your computer system including your server is free from viruses or malware and if it is infected remove the infection as soon as possible. There are many companies that offer ‘blacklist’ services on the internet, the longer you leave the problem, the more ‘blacklist’ systems you will start to appear on.Microsoft Small Business Specialist

If you can’t find any viruses or malware on your computer systems after running a full scan using your current antivirus software I would recommend you try some alternative antivirus software and run another full scan.

Once the infection is removed you can run through a process of requesting your IP addresses are removed from the ‘Blacklist’ To find out which ‘blacklist’ you are on you can try one of the following MX Toolbox, Black List Check, SPAMHAUS or one of the many other ‘blacklist’ providers.

Depending on which ‘blacklist’ you are on you may be able to get your IP address removed within hMicrosoft Partnerours, although some removal requests take days or even longer. I would recommend you are absolutlely certain the virus/malware or server compromise has been resolved before you request removal from a ‘blacklist’ otherwise your removal request will likely suffer unnecessary delays.

Often the reason behind the ‘blacklist’ can be complex and beyond the skills of a normal computer user and you may need to speak to an IT professional to rectify the situation.
