Return receipts on an SMTP relay machine...
Hi all, I'm running qmail on an OpenBSD2.7 as an relay for incoming and outgoing mail to/from the internet and our internal Exchange server. Before the switch to qmail, I was running sendmail. Sendmail had one feature that I can't for my life figure out how to get in qmail. After a mail had been relayed to the internet, sendmail sent a receipt back to the sender. I can't get qmail to do that. I have read qreceipt's man page, but that only seems to apply to users on the local machine. This machine only has root and a couple of daemon users. I realize that I have to patch qreceipt to recognize Outlooks SMTP tag for receipts, but how do I do that? I use a OpenBSD binary install. I use tcpserver to have separate relaying rules depending on where the mail comes from. Could this also be used as an receipt mechanism? I anything is unclear, please mail me. Also, Please point me towards TFM.. Or speculations.. or ideas.. or.. ANYTHING!?!? =) A bit desperate, yep..

So Sendmail on your relay sent a message to the sender of each message it relayed informing them of the fact that it'd relayed the message? And you found this desirable? What if every relay on the net starting doing that? You'd often get 4-5 relay notifications for each message you send. What's the point? I have read qreceipt's man page, but that only seems to apply to users on the local machine. This machine only has root and a couple of daemon users. Yes, qreceipt allows users to confirm final delivery to senders who request confirmation. That's much more reasonable than what you're asking for. I realize that I have to patch qreceipt to recognize Outlooks SMTP tag for receipts, but how do I do that? If you really want to do that, I think you'll have to hack qmail-scanner[1] or implement a custom filter[2]. -Dave Footnotes: [1] http://qmail-scanner.sourceforge.net/ [2] http://www.faqts.com/knowledge_base/view.phtml/aid/2142/fid/206
RE: Return receipts on an SMTP relay machine...
Dave, This function is very, very good when you have a client that can't tell the sender that the message has been received. An example is below. This is generated by sendmail. If I get two (one like this, and one from the receiving client), it OK. I don't like to rely on the receivers ability to tell me that they have received the message.
