-Open the following ports to your server (without it you will not recive email, but you can still send):
   - `25/tcp`: SMTP
-  - `587/tcp`: TLS-encrypted SMTP

-You can change the above default ports through the following variables in the playbook:
+If you don't open these ports, you will still be able to send emails, but not receive any.
 
-```yaml
+These port numbers are configurable via the `matrix_bot_postmoogle_smtp_host_bind_port` and `matrix_bot_postmoogle_submission_host_bind_port` variables, but other email servers will try to deliver on these default (standard) ports, so changing them is of little use.
