Hello, I have a mail server running postfix, and another server running an email archive software which can talk smtp.
Postfix is configured to pass a copy of each emails to the archive, using always_bcc = someuser@archive When an email is received it's copied to the archive properly, so far, so good. Now the problem: I have several customers and domains hosted on the mail server. When customer1 sends an email to customer2, then the email appears only in customer2's archive (it's a multitenant solution). I've managed to narrow the issue, and it seems that the problem is that the archive identifies the customer with the rcpt to: (=envelope) address, eg. EHLO aaa.fu MAIL FROM: <no-reply@...> RCPT TO: <customer2@archive> ... Thus the archive doesn't matches this email with customer1 as well. So my question is that is it possible that when customer1 sends an email to customer2 then to send a bcc email to customer1@archive address, and another to customer3@achive address? Thank you, Bela
