- Sami Ketola:
They do not rely on Date header. Date header is not mandatory and also it's not written on server side. It is written by the sender.
Could you please elaborate on "Date header is not mandatory"? As far as the message format goes, "Date" and "From" are actually the two required headers in every message (see RFC 5322), so I am not quite sure what you mean?
