3.3.5.1 SMTP Header Processing

  • Article

The SMTP message MUST meet the following criteria. If any of the criteria are not met, the SMTP message MUST be dropped, and it MAY be logged. The SMTP header fields are specified in [RFC2822].

  • The To field of the SMTP message MUST contain a single recipient, the Local-DC-Mail-Address.

  • The SMTP message MUST contain a body section.

  • The body of the message MUST use the following MIME options (as specified in [RFC2045]): Content-Transfer-Encoding = base64, Content-Type = image/gif.

  • The Subject field MUST begin with the Unicode characters "Intersite message for NTDS Replication:"<17>

If all criteria are met, the contents of the SMTP message From field MUST be placed in the Sender-Mail-Address working variable. The body from the SMTP message MUST be extracted and the base64-encoding MUST be decoded. The decoded result is Receive-Frame.
