Email is a company’s lifeblood—its main internal and external line of communications. Unfortunately, bloodsuckers galore are out there, seeking to sever those lines.
Panorama9 is constantly on the prowl to make certain that your SMTP server is available and replying, your SMTP DNS name is not blacklisted, and your SMTP server is not configured as an Open Relay, thereby avoiding the aforementioned blacklisting.

What makes Panorama9’s email monitoring monumentally better is that it keeps tabs on SMTP service from the “outside,” which provides inherently more authenticity than in-house monitoring. And if SMTP service is ever unavailable, we’ll fix it ASAP, negating the need for a user to report it.
It’s worth repeating. Panorama9 reduces email downtime and repels spammers.
