You apply header_checks on cleanup. I think the header is added by
postfix after incoming. Personnally I put header_checks in main.cf to
apply filters also when sending. You can use smtp_header_checks if you
want to apply only on sending.

Why don't you remove completely this header in your postfix using for example header_checks ? Received is frequently removed to hide internal IP if you don't need to trace them. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

You need to install a pop/imap server to store and deliver mails. Dovecot is one of them. And it is somewhat easy to install and plug into postfix. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org

But the log shows an IPv6. Did you check your IPv6 A/MX/PTR records ? And the IP seems to be the gateway. Do you use a VPN ? Check your DNS for this IP from Cogent. ___ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
