Sentry 21.7.0 and Mailgun SMTP

[loagencydev]

Hi there,

so after looking around deeply into github issues and the forum, I couldn’t find a solution for the problem I’m facing right now.

Basically I want to configure Mailgun SMTP credentials with our on-premise sentry service, which is running with docker.
The configurations we have (which are set inside sentry/config.yml) look like this:

is there anything we might missing with the configs? mailgun does not showing any logs regarding receiving any request to send a mail, thus there’s nothing on their side.

btw, we’ve already tried the following solutions:

• updating the configs and checking all possibilities with different ports (including 25) and ssl/tls configs (literally checked every combination)
• restarting the whole service and its volumes
• disabling the firewall and in/outbound ports

thanks in advance

What do you see in worker logs? What error do you see when you try to send a test email?

These are the results from test mail:

These are the results when I try to verify my email address:

Yeah it says a timeout connecting to the socket, indicating a networking issue. It may just be some connectivity problem or a firewall preventing Sentry from talking to Mailgun servers.

well, it’s quite strange! as I mentioned before, we’ve already disabled our firewalls, thus allowing all outbound and inbound connections. our IP address is also white listed in mailgun…
might there be something else?

@loagencydev

our IP address is also white listed in mailgun…

Did you verify that you can actually reach mailgun from inside the containers?
