Gmail & other popular email services not receiving email
Kimberly_Boynton is experiencing issues with sending emails from their Discourse instance to Gmail and Yahoo, despite the email being delivered successfully to their own domain account.
The problem appears to be related to authentication, as enabling the SMTP username and password results in a 500 error, while disabling it causes the email to be denied by the providers. Kimberly_Boynton suspects that the issue is due to the Docker container not being validated by the mail server.
With the help of mpalmer, Kimberly_Boynton is trying to resolve the issue by either enabling authentication or adding an IP exception on the Poste.io mail server.
Kimberly_Boynton eventually resolves the issue by finding the external IP of the Docker container using docker inspect <container id> and adding it to Poste.io to allow non-authenticated emails from that IP. mpalmer jokingly attributes the solution to the “rubber duck debugging” effect.
#DISCOURSE_SMTP_PASSWORD: pw # required, WARNING the char ‘#’ in pw can cause problems!
DISCOURSE_SMTP_ENABLE_START_TLS: true
If I enable the username and password it gives me a 500 error about command not recognized. If I don’t, the logs say the email is sent and it DOES send to my account on my domain if i say to, but it does not send to gmail or yahoo emails.
I have an SSL cert that I tested and is valid. I have tried multiple things and spent around 14 hours trying to get this working. I don’t know why its not sending, the same things are used for my other services, and they both are capable of sending to gmail and yahoo.
Hey, sorry, I am just looking at it still. I found it’s being denied by the providers, probably bc I don’t have login enabled, but in that case i can’t because it says the command is unrecognized. I am trying to look into how to enable that (I am pretty sure its bc discourse is in its own docker container sending the email not on the location the mail server is directing from and therefore its not auto validated by the server and needs authentication or for the mail server to allow from that ip without authentication)
Now that i said that i just realized i can allow from a domain in poste.io without signing in… which means i just need to find the ip for the docker container and maybe that will work
Thanks for replying to me, if you hadn’t I wouldn’t have typed that long message and figured it out lol.
