About MailRadar

As a Linux oriented community for sysadmins, MailRadar.com aims to provide unique information and surveys about email messaging and email servers, as well as a range of free tools to help you determine the status of an IP or domain, or the security level of your mail server.

The Team behind MailRadar

Our community is actively involved in Linux related activities therefore we currently support several Linux distributions, such as RedHat Enterprise Linux, CentOS, Fedora Core, SUSE Linux Enterprise Server, Novell Open Enterprise Server, SUSE Linux, Mandrake Linux, Fedora Core, Mandriva Linux, SUSE Linux, Slackware , Debian, Ubuntu Server, Gentoo. We also cover other Unices such as FreeBSD, OpenBSD, NetBSD, Solaris, but development road map includes versions for Windows, Mac OS and other operating systems.

As our community, along with our know-how and competence, increases, we aim to expand our reach and focus to also cover other operating systems.

This project has been initiated and implemented by the Gecad Technologies team, an innovative team with 15 years of experience in messaging, security, and administration.
