Sounds like you need to learn about how SMTP works. RCPT TO is one of the commands used between an SMTP client and an SMTP server. The address listed after RCPT TO is what is called the "envelope recipient" and is the destination address to which the server will deliver or forward the mail. The "To" and "CC" headers in a mail message are just part of the message to a mail server (think of it like snail mail - the post office delivers the mail to the recipient on the envelope and does not care at all to whom the letter inside the envelope says it is addressed). Your initial description makes it sound like something at site3 is parsing the message headers (From, To, and CC) and then attempting to resend the message to those addresses. If true, that is very wrong behavior on the part of site3. Your example says "m...@site3.com" so I assume you are the site3 recipient. Are you running some sort of script on the received message that might be doing this? Do you control the site3 SMTP server or are you just a user there? -- Larry Stone lston...@stonejongleux.com http://www.stonejongleux.com/ > > From: Victor d'Agostino <d.agostino.vic...@gmail.com> > To: postfix-users@postfix.org > Sent: Monday, March 18, 2013 5:45 PM > Subject: Re: Duplicate Emails Sent > > Hi Ed, > > It seems that site3.com smtp server use header recipients instead of SMTP > RCPT TO recipients and also send to the sender ... > > Can you post email headers to check the Received From fields ? > > > Le 18/03/2013 21:51, Ed a écrit : >> Hi All. >> >> The scenario: >> >> From: a...@site1.com >> To: b...@site2.com >> CC: m...@site3.com >> >> After receiving the email CC at site 3, site 3 is sending out emails to >> everyone on the original, >> basically a duplicate email arrives to the sender and everyone in the >> headers. >> >> >>a sends mail to b with me in cc. >> >>me sends mail to everyone in the email headers >> >> I am asking how to stop this behavior.? >> >> I tried in an earlier attempt to post my postconf contents here but was >> rejected due to size. >> >> Thanks >> >> Ed > > >
