What is required in order for MDaemon to consider a message RFC compliant?

In order to pass MDaemon's RFC compliance check messages must:

  1. Be greater than 32 bytes in size (the minimum size necessary to include all required parts)
  2. Have a DATE: header
  3. Have either a FROM: or a SENDER: header
  4. If present, there can be only one FROM: header
  5. If present, there can be only one SUBJECT: header

Messages can be exempt from compliance checks if:

  1. They are from authenticated sessions
  2. The compliance check is disabled
  3. They are from a trusted IP
  4. The FROM: is from a trusted domain
