MPmail Update

Issues receiving emails from Web Central

  • During the last week of August and first week of September, a number of our partners reported issues with email from Web Central being bounced directly by our Roaming Black Lists technology (with the sender receiving a 551 Mailhost is on our global block list.) We worked closely with the team at Melbourne IT to resolve the issue which ended up being a specific customer within Melbourne IT’s network that was sending large volumes of emails from an automated form to addresses that didn’t exist.
  • The Roaming Black List service is one of the tools that we use to help protect our customers from spammers and works by temporarily blocking emails from IP addresses that are sending a very large volume of emails to addresses that do not exist (directory harvest attack), in the hope of collecting real email addresses.

Cryptolocker

  • We are still seeing a high incidence of Cryptolocker being downloaded by users clicking on links.  MPmail on it’s own will stop many of these attacks, however as most of them are links, leading to deeper links — a combined filtering of email and web is required to most effectively stop this ransomware. We are putting together a detailed “best practice” document for MPmail, MPweb and local network policies over the next couple of weeks, but until then — be on the lookout and consider deploying MPweb to block people downloading this nasty Malware.
