Availability
What good is your e-mail system if you can't access it? RestonTech e-mail servers are built on high-availability hardware, and connnected directly to the core internet backbones. Complying fully with well tested standard protocols, it can be accessed by almost any e-mail client, on almost any operating system. All mail is archived daily, to allow full recovery of accidentaly deleted messages. Secondary and tertiary incoming mail servers are located on topologically distinct networks.
Flexibility
RestonTech can provide IMAP inboxes, for shared and multi-tiered access. These folders are accessable via POP for older devices and mail clients. If you already have a mail server in your office, RestonTech can "pre-scan" incoming messages, and only pass through what passes the anti-virus, anti-spam, and other malicious content filters.
Security
All access to the server is encrypted. User names, passwords, and all of the data transmitted to and from the server during reading or sending mail is protected from evesdroppers. This means it is safe to use from unknown and untrusted networks, such as community wireless access points. The system is HIPAA compliant for intra-office communication.

How is mail scanned?

RestonTech has finely tuned the filters for incoming messages. The approach is designed to block the messages that are most obviously malicious (viruses, trojans, phishing, stock scams), without ever blocking a legitamate message.

There are four stages of scanning:

Known sources of spam, viruses, and trojans are blocked according by IP address. These include hijacked servers and workstations, and various businesses known for only sending spam.
Obvious malformed headers and other network level errors are blocked (e.g. the "From" address is from a non-existant domain).
A custom configured anti-spam filter (SpamAssassin) is run on every incoming message. Over 50 tests are conducted, including a natural-language statistical (Beyesian) analysis of the content. Points are assessed for each test, and the point total is used to determine if the incoming message is spam:
- Under 4.0: Message is considered non-spam
- 4.0 - 6.0: Message is marked as potential spam
- 6.1 - 10.0: Error code is returned to sender
- 10.1+: Connection is immediately dropped
Any message that has passed the other tests is now scanned for viruses (ClamAV).

This layered approach blocks over 80% of all incoming messages. Of the messages that pass through, there are some that fall into a grey area-- are they spam or not? This depends on individual users, as some people sign up for promotions that other don't, some people run mailling lists, etc. The built in junk mail filters that most email clients now provide as a feature is ideal for this last, final (and most personal) filter.
