Answer

The administrator can exercise complete control over message processing. Like all GMS products, GMS Communication Server comes with sensible defaults. For example, GMS Communication Server by default removes a number of headers from any messages posted to a list. All of the following headers are removed from each post:

  • Content-Length:
  • Errors-To:
  • Precedence:
  • Return-Path:
  • Return-Receipt-To:
  • X-Confirm-Reading-To:
  • Disposition-Notification-To:

These clauses are added to headers of messages by some mail clients to add additional functionality. For example, the “Return-Receipt-To:” clause will cause a mail server or client to respond by returning a message to the sender.

Can you imagine the effect of sending a list post out to 100,000 people and having a receipt returned for each one of them?
