Describe the bug
SMTP Auth is setup but the mailserver isn't using the details. When I try to send, I get an authentication failure which seems to be due to it not even trying to authenticate. This may be a configuration issue on my side, but there isn't clear documentation currently.
To Reproduce
Steps to reproduce the behavior:
add RELAYHOST, RELAY_OPTIONS and RELAY_PASSWD_FILE to the .env file with the relevant values.
eg
RELAYHOST=[smtp.google.com]:587
RELAY_OPTIONS=
RELAY_PASSWD_FILE=/etc/postfix/sasl_passwd
Expected behavior
Able to send emails via smtp auth
Screenshots
If applicable, add screenshots to help explain your problem.
Docker environment (please complete the following information):
Output of docker compose version
Docker Compose version v2.29.7
Additional context
Looking through the commits, I saw that initially smtp_use_tls=yes was set and tried connecting to the mta and running postconf smtp_use_tls=yes. After this was done, the mailserver was authenticating correctly with the relayhost I use.
