Accept SMTP server with no logins

[improvethings]

I have postfix running on localhost port 25.

In Rocket.Chat /admin/SMTP I have localhost, port 25, no user or password and [email protected].
In /admin/users in the top right, if I click on the + symbol to add a user, it says "In order to send invitation emails you first must configure SMTP settings".

When I choose to send a test email, I get a popup saying, "Success! An email was sent to [email protected]" but an email never arrives. How do I debug this? Nothing seems to hit my postfix mail.log.

Also, what is the purpose of /mailer, there doesn't seem to be an option to save settings there.

Take a look at line 3 of packages/rocketchat-lib/server/startup/settingsOnLoadSMTP.coffee, it only sets process.env.MAIL_URL when host, username and password configurations are set. To fix it, try removing
and RocketChat.settings.get('SMTP_Username') and RocketChat.settings.get('SMTP_Password') from the if statement. Also change line 4 to something like this
process.env.MAIL_URL = "smtp://" + (if RocketChat.settings.get('SMTP_Username') and RocketChat.settings.get('SMTP_Password') then encodeURIComponent(RocketChat.settings.get('SMTP_Username')) + ':' + encodeURIComponent(RocketChat.settings.get('SMTP_Password')) + '@' else '') + encodeURIComponent(RocketChat.settings.get('SMTP_Host'))

@bgomelsky - thanks! @improvethings - or just add a username and password to your postfix if you don't want to change code.
