I am using an internal SMTP server that uses white listed IP addresses for authentication on port 25 (Not Username and Password). How do I configure this to work. I am running Flarum using the sample docker-compose file https://raw.githubusercontent.com/crazy-max/docker-flarum/master/examples/compose/docker-compose.yml
I have configured a smtpd.env file
SMTP_HOST=serverxxx.net
SMTP_PORT=25
SMTP_TLS=off
Docker logs reports no errors.
When I look at email settings in Flarum Admin, I only have the option for smtp, mailgun, mandrill, log
I tried using smtp, but it will not accept my settings without a a username and password, tried putting in a fake username and password just to fill in the fields, I get a very basic Error occured message when the Flarum tries to send an email.
Any ideas?
