    docker-compose exec postfix-mailcow postconf -n | grep -i header gives me:

    header_checks = regexp:/opt/postfix/conf/list_unsub_header
smtp_header_checks = pcre:/opt/postfix/conf/anonymize_headers.pcre
smtpd_sasl_authenticated_header = yes
smtpd_tls_received_header = yes

    and

    docker-compose logs postfix-mailcow | grep prepend gives:

    [unknown] Aha! I thought it was for outgoing emails, like when you send an email from mailcow and it shows to the recipient an “unsubscribe” button 😅

    [unknown]
    Adding line /^Content-Type:/i PREPEND List-Unsubscribe: <mailto:unsubscribe@mydomain.com> straight to anonymize_headers.pcre then running docker compose up -d and docker compose restart postfix-mailcow fixes it! 🫣
    Now there is an List-Unsubscribe header in the source! As you said it might be overwritten after an update but at least it works for now until there is a better solution! Thank you!!! 🙏

      • In How to implement Global List-Unsubscribe Header

        Yes, the List-Unsubscribe header is missing :/
        By the way this is the contents of /home/mailcow-dockerized/data/conf/postfix/list_unsub_header

        /^Content-Transfer-Encoding:/i PREPEND List-Unsubscribe: mailto:<unsubscribe@mydomain.com>?subject=unsubscribe>"

        I tried the steps and nothing yet! 🤔 does it take some time to work ?

            I tried running docker compose down then docker compose up -d but nothing.
            Also the header_checks line that was added in the /home/mailcow-dockerized/data/conf/postfix/main.cf disappeared

                I tried and nothing still.. 😕

                What i literally tried is:

                1. added new line header_checks = regexp:/etc/postfix/list_unsub_header to /home/mailcow-dockerized/data/conf/postfix/main.cf
                2. created list_unsub_header next to main.cf in /home/mailcow-dockerized/data/conf/postfix/list_unsub_header
                3. ran docker compose up -d
                4. restarted postfix-mailcow form mailcow UI

                Please where did I mess up? I have been trying this for days.. 🙏

                    Exactly! I am having the same issue, I want to add a global List-Unsubscibe header and I followed the mentioned Mailtrap Icon tutorial

                    , but still not working.
                    There is a confusion about how to do this correctly, one of which is which main.cf should be edited? the one in system’s /etc/postfix/ or the one in the mailcow working directory which is in my case /home/mailcow-dockerized/data/conf/postfix/, i tried both and none worked, also when i change the main.cf in /home/mailcow-dockerized/data/conf/postfix and i restart postfix-mailcow process, the main.cf gets back to previous state..
                    I would really appreciate if someone could give an explicit step by step guide to us newbies, its just too confusing.. 🙁 !
