Policy banks are sets of Amavis configurations that are applied to specific email senders. You can set-up policy banks to allow clients on your internal network to bypass Anti-spam/Anti-virus scanning, allowing particular senders to attach files that are banned for other senders, etc.
MYNETS - Mail that originated from your networks. Networks are defined under Warden -> Settings -> Content Filter Settings -> My networks
SUBMISSION - Mail that was sent using the submission or SMTPS services (ports 587 or 465).

Whitelist senders (Spam Filter) - whitelist_sender_maps
Use envelope sender lookups to ensure delivery from whitelisted senders even if the message would be recognized as spam. Effectively, for the specified senders, message recipients temporarily become "spam_lovers".
Whitelisted senders also suppresses inserting/editing the tag2-level header fields (X-Spam-*, Subject), appending spam address extension, and quarantining.
Note: Whitelisted senders only applies to spam filter checks. All other checks will still be performed.
Default: empty
