The benefit of having your own email server (and not proprietary) is the level of customization that can be done to make the server effective and efficient based as per our requirements.

The software fully supports multi-tenancy and delegated administration for hosting and service providers.

Following are the security features:

• SSL implementation for secured communication over the internet
• Enable no one to access the server via web interface from outside the organization but rather make it mandatory for all the employees to use it within the organizations network.
• Assurance for Spam and Antivirus filtering
• Blocking of extensions like .exe, .msi etc. that may be a virus or a Trojan
• Enable reverse proxy that will ensure the traceroutes never reveal the original IP address of the email server.
• Monitor emails of employees in real time
• Block specific domains where employees cannot send emails
• Black/White listing of email domains
• Role-based delegated administration to create domain or limited administration settings per account
• No persistent caching of user data

Key security framework methodologies:

• Network privacy and server authentication – is able to use SSL/TLS encryption of all network communications (signified by “https:” URLS)
• Client authentication token required – “auth” tokens contain a cryptographically secure representation of the user’s individual and machine/network identity, as well as an expiration time. This auth-token prevents classic data-injection attacks on the server.
• End-to-end data encryption – has multiple implementation options for encryption between the client and server. Is compatible with encryption technologies such Secure Multipurpose Internet Mail Extensions (S-MIME) or Pretty Good Privacy (PGP).

Along with these features you can also ensure the real time backup of email server which will aid in Business Continuity and Disaster Recovery Management.

Native hierarchical storage management – allows for cost effective multiple GB mail boxes by seamlessly moving off older messages to commodity storage

Multi-domain support – multi-tenancy domain-level administration and domain-level re-branding

Service provider tools – such as limiting number of mailboxes per domain or allowing domain administrators to set their own storage quotas and security policies

Extensible with web services – connect other inter / intranet applications and data source via complete set of SOAP / REST web service APIs

Native integration with popular clients – server syncs with Microsoft Outlook (via MAPI), Apple Desktop (iSync), Novell Evolution and popular mobile devices with no additional server needed
