You seem to be talking about the SMTP ports, right? What do you suggest instead? Port 465 with SSL/TLS and only as a secondary solution 587 with STARTTLS? The current statement was based on [1] which recommends not to use port 465 but instead only 587 with STARTTLS. Granted, with STARTTLS, you have some additional attack vectors.
