Mail server

Number of users

Mail Server with integrated WebClient is at the heart of IceWarp's communication solution. Number of users determines the maximum number of mailboxes while domains are always unlimited.



Fully integrated Kaspersky antivirus engine with real time updates and powerful multi-threaded processing capable of scanning over 4,000 messages per second.


Highly effective and accurate dual-layer engine based on industry standard Spamassassin and zero-hour outbreak protection powered by CYREN.

SSL Certificate

IceWarp Certification Authority recognized by 99% of browsers offers three types of server certificates that allow a company to establish secure and trusted communication from WebClient and mobile devices.

Single domain - domain validated

This option will create a certificate for a single domain, e.g.

Wildcard - domain validated

The wildcard certificate will allow you to cover all sub domains relating to the primary domain, e.g., and covered under one * certificate.

Multidomain - domain validated

The multidomain certificate can combine 3 or more different domains and subdomains in one easier to manage package but otherwise it is similar to multiple single domain certificates.
