Can't send mail on 16.04 - DigitalOcean

installation
1

I’ve been looking for the answer all day, nothing.

  • I’m doing a fresh install via the first rails app guide on github.
  • Using a 1GB DigitalOcean droplet
  • Using NameCheap’s private email server.

Here is my app.yml:

DISCOURSE_HOSTNAME: smocks.me

  ## Uncomment if you want the container to be started with the same
  ## hostname (-h option) as specified above (default "$hostname-$config")
  #DOCKER_USE_HOSTNAME: true

  ## TODO: List of comma delimited emails that will be made admin and developer
  ## on initial signup example 'user1@example.com,user2@example.com'
  DISCOURSE_DEVELOPER_EMAILS: '*****@gmail.com'

  ## TODO: The SMTP mail server used to validate new accounts and send notifications
  # SMTP ADDRESS, username, and password are required
  # WARNING the char '#' in SMTP password can cause problems!
  DISCOURSE_SMTP_ADDRESS: mail.privateemail.com
  DISCOURSE_SMTP_PORT: 587
  DISCOURSE_SMTP_USER_NAME: admin@***.me
  DISCOURSE_SMTP_PASSWORD: "*****"
  #DISCOURSE_SMTP_ENABLE_START_TLS: true           # (optional, default true)

Would appreciate any help on this.
P.S. I ran the more command on my Discourse log, it says Mail Sent!

Me paso y coloque el puerto 2525

Didn’t work. Before I even checked the log I did telnet mail.privateemail.com 2525 and I got hit with:

telnet: Unable to connect to remote host: Connection refused
4

Also ran sudo ufw allow 2525/tcp @Mecanicos_Argentinos

Don’t DO block port 25 on new accounts now?

Afaik Mailgun on a secure port is still fine, otherwise you’ll need to contact support.

6

Can you telnet to port 587 of mail.privateemail.com? If not, you’ll need to open a ticket with Digital OCean to get them to unblock the port, or get mail.privateemail.com to accept connections at port 2525.

7

Port 587 works. I contacted DO about this a few hours ago, havent heard anything. This has happened with multiple VPS hosts.

Oops. I didn’t notice this before.

You need to check the logs at mail.privateemail.com, as it’s accepting mail from Discourse but not delivering it.

Or it’s in SPAM.

Job exception: Error connecting to Redis on localhost:6379 (Errno::ECONNREFUSED)

It says “Mail Sent” 4 times at the bottom of my log.
