Ill just be honest here, i have no idea about anything related to email or docker etc so dont expect my to understand verbose questions. But heres whats going on, i have a web server already running on the root of the domain (lets say site.com). its using nginx as the reverse proxy. i already have it configured. the config file for that server uses this as its server name.
server_name site.com www.site.com. I also have
mail.site.com as a working subdomain. I do not know why, but when i go to that subdomain my website still displays on it. it shouldn’t since the nginx server block does not specify to use that, just www and the main domain. What i want is for the mailcow web interface admin panel to be accessible only through
mail.site.com and the rest of the website to be as is. i also specified
mail.site.com as the FDQN thing during the generate_config.sh setup but im not sure if that was correct. however when i run
sudo docker-compose up -d it errors out on the nginx step. The error log is as follows
Starting mailcowdockerized_nginx-mailcow_1 ... error
ERROR: for mailcowdockerized_nginx-mailcow_1 Cannot start service nginx-mailcow: driver failed programming external connectivity on endpoint mailcowdockerized_nginx-mailcow_1 (not_sure_if_i_should_redact_this): Error starting userland proxy: listen tcp 0.0.0.0:443: bind: address already in use
ERROR: for nginx-mailcow Cannot start service nginx-mailcow: driver failed programming external connectivity on endpoint mailcowdockerized_nginx-mailcow_1 (not_sure_if_i_should_redact_this): Error starting userland proxy: listen tcp 0.0.0.0:443: bind: address already in use
ERROR: Encountered errors while bringing up the project.
Its obvious whats happening here, the mailcow dockerized version of nginx conflicts with the existing nginx running. When i
systemctl stop nginx on the server and then run
docker-compose up -d it works, and the mailcow admin panel shows up on all domains however, mail.site.com, site.com, www.site.com.
What i need is for mailcows nginx to not conflict with the existing nginx running. and also for my existing nginx website to not show up on the “mail.” subdomain (because right now it is and idk why), and for the mailcow web interface to show up only on the
mail. subdomain. For the record of what im doing, i own my website, and i want to create a firstname.lastname@example.org email address that users of the site can contact, and i, through the sites web interface, and communicate and respond back to.🙂
