Get your facts straight
As the authors of @Mail we have to disagree with your false acusations.
Firstly, @Mail does work under Suse Linux. The dependencies of the software are Apache, perl , gcc and mysql. If these are available under your OS the software can be installed.
Secondaly, the accusations of our technical team resetting root passwords, opening firewalls and exposing systems to hackers via SSH and Webmin are completely wrong. You should get your facts straight before you bad mouth a company without any backing to your claims.
Thirdly, we provide an online demo, download evaluation and a 30-day refund policy on the software. So you had plenty of opportunities to evaluate the software.
