Hello: I don't think this is necessary. First, this headers should be handled by the application (and indeed can easily be done as you pointed out). Second, there is a conventional "X-Loop" header used and supported by many MTAs.
http://www.ninebynine.org/IETF/Messaging/draft-klyne-hdrreg-mail -00.html#hdr.X-Loop Most delivery agents do this automatically. It is extremely unlikely that two modern SMTP servers enter in a delivery loop, because this used to be such a big problem before. In any case, this should be handled at the server level, and SmtpProt is intended to be an SMTP client. dZ. -- DZ-Jay [TeamICS] http://www.overbyte.be/eng/overbyte/teamics.html On Mar 25, 2008, at 15:27, Bjørnar Nielsen wrote: > New property: > > property XAutoGeneratedReply : Boolean read > FXAutoGeneratedReply {Bjørnar} > > > write FXAutoGeneratedReply; {Bjørnar} > > > > The reason for using this is to tell the receiving mailserver that it > should not answer this email with "I'm on holliday" or similar.
