[Bug]: Issues with login and mail

Issue Description

I setup OpenSign self-host on Linux with Docker using the command in the docs.

I logged in via my customer domain on https and created a new admin user and signed in, was shown the welcome tutorial, clicked to verify my email and realised it wouldn't work as I hadn't entered my mail server details.

I then edited .env.prod to add my SMTP credentials

I did a docker compose down and docker compose up to recreate the containers and force them to re-read the config.

I can now no longer login via my custom domain (not sure why?) but can still access http://localhost:3000 via port forwarding (it's running on a VPS). My saved username (email address) and password are not recognised for login.

I then tried to reset the password but was receiving a 'Please setup mail adapter' error.

Checking the logs I was also initially getting a 'please enter valid SMTP credentials' error in the logs - adding a ' around my password (even though it didn't include spaces?) now seems to not generate that error however the 'Please setup mail adapter' error remains. I have also confirmed the SMTP server/username/password by setting up on Thunderbird on a separate machine and all work as expected. Port is 465 so I've tried adding SMTP_SECURE=true but it didn't seem to make a difference.

# Email mailgun or set SMTP_ENABLE true to use SMTP config (The app will not initialize if any of these 3 variables are>
MAILGUN_API_KEY=
MAILGUN_DOMAIN=mail.yourdomain.com
MAILGUN_SENDER=postmaster@mail.yourdomain.com
SMTP_ENABLE=true
SMTP_SECURE=true
SMTP_HOST=smtp.domain.com
SMTP_PORT=465
SMTP_USER_EMAIL=me@domain.com
SMTP_PASS='REDACTED'   # if your password includes spaces then write password in single quotes

Expected Behavior

Be able to login at my custom domain Be able to send password reset email

Current Behavior

As above - only able to login via localhost and cannot send mail

Steps to reproduce

As above - setup fresh then edit .env.prod file
