I'm trying to setup email with postfix image and msmtp from php. Sending emails from command line works from wordpress container to postfix using msmtp (I'm using docker compose but I think it's not related). But in php it don't work.
Postfix log show this:
Feb 14 12:00:09 36a1774df087 postfix/smtpd[141]: connect from volume_wordpress_1.volume_default[172.23.0.4]

php config look like this:
sendmail_path = "/usr/bin/msmtp -C /etc/msmtprc -t -i"
The same command work when I run it from terminal. But from php it show above error.
Do I need to change wordpress@10.39.91.81 (it's intranet public machine address, wordpress is name of the service in docker-compose.yml)? How can I do that?
