Port requirements for Postal V3

[jshapiro2]

Hello,

With the remove of RabbitMQ in V3 I just wanted to confirm the ports that need to be open to the internet. Please confirm.
PORTS: 25, 443, 80, 53, 8080

Incoming

• TCP:80 and TCP:443 for the web interface (and tracking)
• TCP:25 for the SMTP server

Outgoing

• TCP:25 for sending e-mails to other SMTP servers
• TCP:80 and TCP:443 for sending e-mails to HTTP endpoints and webhooks
• TCP:53 and UDP:53 for DNS resolution
• TCP:3306 for the MariaDB database if it isn't on the same host as the Postal application

If you have SMTP or HTTP endpoints which use other ports you will also need to allow these.

You don't normally need to open 53 to the internet, it probably gives you a bad time unless you are hosting your own DNS.

8080 doesn't sound particularly related to Postal.
