Friendly Relations System

The Friendly Relations System or "Friends" is a spam prevention system that will check incoming mail based upon a list of known email addresses. The Friends system can operate in the following modes:

• Kids safe mode - Only accept mail from known friends
• Request confirmation from sender
• Allow all mail through - Friends system disabled

Kids Safe mode

This is the highest level of safety. Mail is only allowed through if the inbound email address is in the list of known friends. If this is not the case the inbound message is bounced with a notification that this person is not accepting mail from unknown senders.

This safe mode message can be customised at the server level by creating a text file "kids-safe.eml" in the surgemail directory.

Request confirmation mode

In this mode, if a message is received that is not from a known users an email is sent to this person requesting them to respond to confirm that they are human. If a response is received the original message will be delivered. On a regular basis a status report message is sent to the user providing information of the friends system and any mail pending delivery.

The Friends system may be temporarily disabled if an urgent message is expected from an unknown address using the "Un-Block" button. This will effectively turn either the "Request confirmation mode" or the "Kids safe mode" into "Allow all mail through" for a period of three hours.
