However, by hosting your own servers then you must have a static IP on the internet the mail to route correctly. The issue is sometimes SPAM black lister actually list blocks of IP addresses rather than just one. The reason being is businesses can have more than one IP address on the internet, in fact home users can, so simply to deny one IP might not stop the spamming. So if you have a static IP address(es) which never changes, what do you do to overcome this issue as you can't simply turn off and on the router? Thankfully, there's a tool on the internet that checks whether your IP address(es) are blacklisted or not. Goto, http://www.mxtoolbox.com/blacklists.aspx, type in the IP address of your server on the internet (your IT professional can tell you this) and click "Search". If any return as listed then you contact that anti-spam company and request for it to be removed.
