Hello all, I try a solution to insert a counter number into the Subject line for any message leaving the email server(sent by a local client through local interface). I used the example shown at http://www.postfix.org/FILTER_README.html but the counter appears in every message hitting the email server.
/etc/postfix.master.cf: # ================================================================== # service type private unpriv chroot wakeup maxproc command # (yes) (yes) (yes) (never) (100) # ================================================================== # filter(count) internal 127.0.0.1:smtp inet n - n - - smtpd -o content_filter=filter:dummy 192.168.0.1:smtp inet n - n - - smtpd -o content_filter=filter:dummy 89.137.101.102:smtp inet n - n - - smtpd -- Best regards, Gmail-teopro mailto:teo...@gmail.com
