The "Host-based email" rule shows "Ports 25+" because it includes multiple ports:
- POP3 (Ports 110,995)
- IMAP (Ports 143,993)
- SMTP (Ports 25,465)
There may be more that I've missed but the main point is that there are multiple ports it is classifying.
The "Windows file sharing" rule has a similar name and multiple port classification.
However, for this rule, it lists the ports under the name.
