Cox's server side email filter rules

Hello All --

I tried this question a month ago. That query is now locked, and was never well answered. So as requested, I'm starting again.

I'm looking for a tutorial on the server-side email filters.  Something that gives the basics that trial and error has not revealed as of yet.

Questions such as:

• What is the limit on the number of rules?
• What is the limit on the number of conditions per rule?
• What is the limit on the number of actions per rule?
• Are rules case sensitive?
• What is the difference between 'contains', 'matches', and 'regex'?
• Similarly for 'contains not', 'matches not', and 'not regex'?
• Similarly for 'exists' and 'does not exist' etc.
• After submitting, how long before the rules are effective?
• If using 'From is exactly' how much of the From line is checked:
  • the entirety?
  • Including 'From: '?
  • just between the angle brackets?
  • including the angle brackets?
• If 'Keep' is the action, where is the email kept?
• if 'Discard' is the action, where is the email put?
• Where does 'Starts with' start and 'Ends with' end? See 'From' above.
• Do the Spam/Not Spam icons have any Bayesian logic associated with them?
• etc.

The list goes on.  I'll settle for a pointer to a comprehensive discussion. Maybe this will become that.

On the subject of 'Alaskan Seafood' I have found this combination on any condition to work:

• From Regex /alaskan/i
• Subject Regex /(seafood|alaskan)/i
• Body Regex /alaskan/i
• File Into Select Folder Spam
