Using the same email address for both sender and receiver

how do you do this with php and for many users?

I've seen sites where a user A fills out a form which send an email to user B. User B replies to an address like [e-mail], and user A can reply to that same email address. However, user C,D, etc. also goes through this same process, and they all use the email [e-mail].

All emails end up to the right person, however, presumably because there's an identifier in the subject line (e.g., [ID=34632]) that forwards the email to the right person. How do you set up this kind of system? Where can i go to look up more details on something like this?

thats an interesting one

do you have any of these emails? You can look at the headers and see if there is anything in there as well, there may be some identifiers there as well.

I haven't seen a system exactly like that, where users interact through an intermediary address. I am not even sure of the use. I would think an internal email system like the stickymail we have here would be much better. I can think of ways to do this but as soon as a user removes that ID, as you say, the message is going nowhere.

i think elance uses a system like this. one reason why i think this might be helpful is that we have clients who often have such forms, that their visitors fill-out. typically, we put the visitor's email in the from field, when it is sent from our site, with a header like (inquiry sent from your site, etc.).

the problem is i think is that the messages someties get labeled as spam, since the "from" email address (the user) doesn't match with our server's IP and doesn't get accepted. hence, we thought it might help if the "from" address matched that of our server (something like [e-mail]), but the client could still just hit reply and make sure it got to the right user. just a thought; other ideas for avoiding being tagged as spam with a system like ours?
