Hi All. I am experiencing an issue with the following:
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. >>m...@site3.com sends mail out to everyone in the FROM and CC upon receipt of >>the mail I am asking how to stop this behavior.? Site 3 logs and postconf follows Logs ---------------------- Mar 14 10:27:41 mail postfix/cleanup[5265]: 10E7BE1C0A: message-id=<E72852EF80963148B21E9046E0C9BDC82863FEC1@mailbox-2010.SECEP.local> Mar
