Hello, Once in a while I have to send messages thousands of users that are listed in a dynamic database. Is not viable for me to use a mailing list manager. To handle bounces I use VERP by connecting to the Qmail SMTP server directly like this: HELO localhost MAIL FROM:<[EMAIL PROTECTED]@[]> RCPT TO:<[EMAIL PROTECTED]> RCPT TO:<[EMAIL PROTECTED]> RCPT TO:<[EMAIL PROTECTED]> DATA Headers: here Message here. . QUIT Qmail delivers messages to the remote MX hosts of domain1.com, domain2.com, domainn.com and if that is the bounces are returned as expected to: [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] However, if instead of bouncing in the remote hosts, the messages bounces right in the local host on which qmail is running and to which messages are relayed, instead the above, qmail waits for the message queue time limit and bounces a single message to [EMAIL PROTECTED] noticing the bounced addresses. I was expecting to get separate bounced messages to be delivered to the VERP address after expanded. I am doing something wrong or qmail is just not supposed to work like I expected? Another problem is about some SMTP servers do not set the To: header of the bounces to the return-path address of the messages sent that should have been the VERP address after expanded for the original recipient. Anybody knows a way to ensure that the VERP expanded address can be recovered? To handle the bounces I have a POP3 based dump account to which all unknown addresses for phpclasses.UpperDesign.com are delivered. I just don't seem to be able to make the original recipient address be extracted because not all SMTP servers set the To: or any other header with the original message return path.
