Re: [twsocket] Proposal for new feature in OverbyteIcsSmtpProt.pas
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.

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. Two
mailservers could send each other mails in definite if no one breaks
the loop. So if you are sending an autogenerated mail, set this flag
to not get a autogenerated mail back.
In procedure TCustomSmtpClient.Data;
if FXAutoGeneratedReply then begin

FHdrLines.Add('X-Autogenerated: Reply');

Re: [twsocket] Proposal for new feature in OverbyteIcsSmtpProt.pas
I did not know of this header-field.
Why not add properties for both? The xautogeneratedreply works for my purpose
and the mailservers I have testet against.

Regards Bjørnar Well, because delivery loops are a server problem, and a mail user agent not only should not take the burden of protecting against them, but cannot be trusted to do so (after all, if a server is vulnerable to this, a MUA will most definitely be the attack vector to it). Have you really encountered a delivery loop with a mail server? If so, you should communicate it to the server administrator, as this is usually a configuration problem. dZ. -- To unsubscribe or change your settings for TWSocket mailing list please goto http://lists.elists.org/cgi-bin/mailman/listinfo/twsocket Visit our website at http://www.overbyte.be
Re: [twsocket] Proposal for new feature in OverbyteIcsSmtpProt.pas
I have made a sollution where I send a receipt to the sender of an email, telling, Thanks for your reply, your case nr is: #234 etc. The loop is when the mail I send the receipt to is a similar solution telling me their case nr etc. Off course I break the loop when I get the second reply, but I don't want any replys. I don't want a receipt back from my outgoing receipt. This is why I want to set this header-info.
