Edit, i figured it out in the yaml file
the quotes around some of the entries were stopping from being read. this is what i used ,
DISCOURSE\_SMTP\_ADDRESS: mail.the
DISCOURSE\_SMTP\_PORT: 465
DISCOURSE\_SMTP\_USER\_NAME: accounts-no-reply@
DISCOURSE\_SMTP\_PASSWORD: X
DISCOURSE\_SMTP\_ENABLE\_START\_TLS: false
DISCOURSE\_SMTP\_SSL: true
DISCOURSE\_SMTP\_AUTHENTICATION: login
DISCOURSE\_SMTP\_DOMAIN: t
DISCOURSE\_DEVELOPER\_EMAILS: info@
DISCOURSE\_NOTIFICATION\_EMAIL: accounts-no-reply@
and default in the samples
has quotes around alot of them like this
DISCOURSE\_SMTP\_ADDRESS: ‘mail.’
the quotes were causing the domain, email and others to not be read for some reason.
no matter what i do, i cannot get discourse to use a port for email other than 25, running on the standalone yml, ive even tried it in the yml, forcing it and no go kinda out of options at this point lol … not sure if this is a bug or not
[SMTP OVERRIDE] Configured SMTP: {:address=\>“mail.”, :port=\>465, :domain=\>“th”, :user\_name=\>“accounts-no-reply@m”, :password=\>“”, :authentication=\>:plain, :enable\_starttls\_auto=\>false, :ssl=\>true, :openssl\_verify\_mode=\>“none”}
Testing sending to y using mail.:25, username:accounts-no-reply@ with plain auth.
======================================== ERROR ========================================
Connection to port 25 failed.
====================================== SOLUTION =======================================
The most likely problem is that your server has outgoing SMTP traffic blocked.
If you are using a service like Mailgun or Sendgrid, try using port 2525.
i also had to force it not to use [example.com](http://example.com) as my domain as it kept forwarding me to it lol. very buggy XD

Hallo, welke SMTP-provider gebruikt u? Heeft u ook al geprobeerd de poorten te wijzigen naar 2525 of 587?

de mail draait op de webserver van een klant waar ik via cpanel toegang toe heb, vrij zeker dat het sendmail op linux gebruikt. er is echt geen reden waarom ik poort 25 voor smtp nodig zou hebben, denk ik. dat is als je je eigen e-maildienst host. niet smtp. wat ik ook in de yml verander, het probeert altijd poort 25 te gebruiken.

mij werd verteld dat als je probeert uit te bellen via poort 25, je IP-adres onmiddellijk op de zwarte lijst wordt gezet.
ik weet niet zeker of dit `standalone.yml` deel uitmaakt van een #advanced-setup

Yeah the standalone.yml is for if you have to use a non standard port and proxy on your webserver. For example I have it running on 127.0.0.1:3000 and nginx proxies it to 443 because I have 6 websites running on the same server so nginx can have many websites on the same IP address.

Yeah running your own mail server on port 25 these days isn’t a great idea most email providers have blacklisted entire vps subnets.
