SurgeMail spam and virus prevention

This e mail server offers advanced features to identify undesirable spam email, block virus infected mail and prevent abuse of your mail server by spammers. Naturally these features can be individually configured.

Open Relay database check

Integrated Open Relay check connecting to any external ORB database to ensure the sender is not blacklisted for sending spam email.

Sender behaviour limitation

SurgeMail e mail server has dozens of configuration options to directly block or tarpit users or servers identified as abusing the mailserver. These include banning by sender IP address, recipient mail address, from mail address; limits on number of recipients per email, maximum bad addresses in a row, email per sender IP address and maximum messages to a single mail account.

Virus scanner integration

SurgeMail e mail server will integrate with any external command line virus scanner that has the option to delete mail if it contains a virus. eg This allows you to use for example Command, Sophos or Norton virus scanners. See here for details.

For Windows we recommend "avast! for SurgeMail" based on ALWIL Software antivirus technology which is fully integrated.

SmiteSpam anti-spam system

SurgeMail has support built in for the SmiteSpam spam detection system when used with the SmiteCRC filter. SmiteSpam uses a combination of filter-rules and fuzzy matching to correctly identify over 98% of spam. The spam messages are marked with a header so individual users then choose their own 'level' of spam tolerance.

Typically the system admin bounces 'definite' spam and allows users to sort through 'dubious' spam after their mail client has put it into a 'suspect' folder.

Spam to spam-trapping addresses can be automatically submitted using SpamBot.

Advanced mail rules

Using elaborate rules, customised policies can be setup for mail forwarding, archiving and filtering. Filtering will typically take some form of action on messages identified as spam by SmiteSpam or external spam identification filters. An alternative use for filtering is to limit mail based on content.

eg this could allow you to setup policies that

• mail identified as almost certainly spam is either dropped or bounced
• mail with undesirable subject matter in body or subject line is bounced

Friends only system

The friends only system allows users to opt to receive messages only from friends. Non friends are automatically questioned to determine if they are human. All mail from non friends is held pending on the server until the user decided what to do with it. Status reports are sent to the user on a regular basis to provide information on the Friends system and any mail pending delivery.
