(FAQ) What is required for MDaemon to consider a message RFC compliant? Print

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
