The best e-mail security gateway

  • October 02, 2025
  • Review provided by G2

What do you like best about the product?
I'm a Linux enthusiast and spent a few years developing a mail gateway with Postifx, SpamAssasin, and other security tools. When I first discovered LibraEsva, I thought this was the goal of all my work: excellent design, a comprehensive and intuitive user experience, designed for multi-domain and multi-client management. It also includes many other security features: the ability to sign outgoing mail with DKIM (without having to configure the internal MTA), sandboxing for URLs and files, and the ability to remove active scripts from attached documents, easy to integrate with many mail system. But what I really appreciate is the detailed message view: I can see everything about an email, its delivery, and even whether it's not delivered (which is important). I can inspect the message header and help the client pinpoint the cause of delivery issues. Finally, their technical support is fast and effective. A heartfelt thanks to the LibraEsva team!
What do you dislike about the product?
To be honest, I don't think I have anything negative to report about this solution.
What problems is the product solving and how is that benefiting you?
LibraEsva helped me solve the huge problem of unwanted email traffic and gave me the opportunity to offer to my customers excellent e-mail system protection.

What do you like best about the product?
I have been using Libra for many years, and it has never ceased to combine remarkable effectiveness with surprisingly low hardware and configuration requirements.
What do you dislike about the product?
I can't find any faults with its use. Perhaps some configurations could be moved to the mail domain level rather than the appliance level. If you use one appliance for each domain, there are no problems.

Spam control with ease of use for the end user and verification of the danger of attachments and links.
