Can I properly track an SMTP message round-trip?
Posted on 2009-04-09
I've never had a request like this before, so I need to post this question in order to find out if this is possilble?
Our web app sends out smtp messages to users upon request.
I've been asked if it 's possible to put an ID in our outbound smtp messages from our web-app so that when a user replies to them and they come back in .. we can associate the reply to the original email, by retrieving the ID from the reply message.
Is that posible in the realm of smtp messaging? We use a windows socket to connect to our smtp server and then output the message thru code .... so, there is no limit to what we can put into the smtp message.
I guess what I am asking is .. is there some place in there that I can put something as a unique ID (that I provide) that will ALWAYS come back in the reply message? Obviously, the body is not reliable as the user may delete the original text.
Thx, in advance, for any help in this regard.
