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`:
```plaintext
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`!

It happened to me, and I set the port to 2525.

Didn’t work. Before I even checked the log I did `telnet mail.privateemail.com 2525` and I got hit with:
```Trying
telnet: Unable to connect to remote host: Connection refused
```

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.

Can you telnet to port 587 of [mail.privateemail.com](http://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](http://mail.privateemail.com) to accept connections at port 2525.

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](http://mail.privateemail.com), as it’s accepting mail from Discourse but not delivering it.
Or it’s in SPAM.

Got this nasty mess:

Uh Ok. I got the email… but I got 4 of them? Could this be from previous tries
