NodePing's monitoring can check each of your email servers on a range of RBL's (Real Time Blacklists) and notify you by SMS, email, twitter, or voice call immediately if your address shows up on any of the RBL's we watch. The system is easy to use, reliable, and extremely cost effective.
Most email services implement a variety of measures to try to limit spam. One of the most common steps taken almost universally is the use of real time blacklists (RBLs), which attempt to list services that are known to generate or relay spam. These lists are not perfect, and every once in a while a legitimate email server is listed on one or more of these lists. If that happens to your server, other email services across the internet will start rejecting your mail. So it is very important to maintain monitoring of the commonly used black lists to make sure email from your servers is not blocked. NodePing's RBL monitoring makes this easy.
RBL monitoring is just one of the great monitoring tools NodePing offers. With your NodePing monitoring account you also get monitoring for SMTP, IMAP, POP, web sites, DNS, FTP, and a number of other Internet services.
