Some of my messages sent by SMTP in the Oberon subsystem of A2 bounce 
with a report such as this.

    550-5.7.1 [] Our system has detected that this message is not
    RFC 550-5.7.1 5322 compliant. To reduce the amount of spam sent to Gmail,

    end of DATA command)

The reference to RFC 5322 is non-specific.  Most incidents are for 
Gmail addresses but some other addresses have produced bounces.
