DNS lookup fails #12

Closed OtherwiseJunk closed 2 years ago

OtherwiseJunk commented 2 years ago

I pulled the image for use as an SMTP server for a Mastodon instance.

it looks like the request hits the SMTP server just fine, but then the SMTP server fails its DNS lookup:

I'm using the image here in my docker-compose with no environment variables provided, basically just running a vanilla image.

I assume I just have something mis-configured and it's failing to get the dns info because of it?
