+Postmoogle runs an SMTP email server and allows you to assign mailbox addresses to Matrix rooms.
 
 See the project's [documentation](https://gitlab.com/etke.cc/postmoogle) to learn what it does and why it might be useful to you.
 
 ## Prerequisites
 
-### Ports
+### Networking
+
+Open the following ports on your server to be able to receive incoming emails:
 
-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
+  - `587/tcp`: Submission (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
-# on-host ports
-matrix_bot_postmoogle_smtp_host_bind_port: '25'
-matrix_bot_postmoogle_submission_host_bind_port: '587'
-```
+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.
