Useful account rules

OversizeINBOX
This is a default Rule for mail accounts created after 2001 September 1. Create a message directory folder called OversizeINBOX. When you create the folder specify the filename as OversizeINBOX.mdir to override the default message box format. Then write a rule so that any incoming messages larger than 100KB are stored in OversizeINBOX and discarded.

Sample:

     IF Message Size greater than 100K
     THEN
     Store in OversizeINBOX
     Discard

NotifyMail
Use a NotifyMail client on your computer. Create this rule so that all incoming messages trigger instant notification. The priority of this rule should be after any redirection or anti-spam rules that will discard mail and before local processing like OversizeINBOX that will store the message and stop processing.

Sample:

If you use NotifyMail you should also disable polling for new messages or poll infrequently like once every 30 minutes.

Anti-Spam
This Rule moves the incoming messages with a digital score 85 and greater to the "Spam" mailbox. This rule should either appear first and the folder named Spam needs to exist. Read the Spam Catcher Plugin page for additional details.

Sample:

    IF Header Field is X-SpamCatcher-Score: * [XXXX*]
    IF From not in #addressbook
    THEN
    Store in Spam
    Discard

The following ratios are used:

digital    Bar score
0          []
1-39       [X]
40-76      [XX]
77-84      [XXX]
85-90      [XXXX]
91-99      [XXXXX]
100        [XXXXXX]

Incoming messages with the Heabas haiku header are not scanned by Spam Catcher; because it doesn't appear that as of v1.9 Spam Catcher can directly support it.
