Question remove legacy authentication protocols, such as POP3 and IMAP

Server operating system version

ubuntu 20.04

Plesk version and microupdate number

18.0.49

We are seeing requests from customers via their insurance companies to enhance email security with phrases like "remove legacy authentication protocols, such as POP3 and IMAP"

This sounds like a glorified advert for 365 or google

However, is there anyway to allow similar through plesks offerings?

O365 can do it because they have a "closed" system with alternative protocols. For normal Internet users it is neither necessary nor a standard. If you believe it is important to have a replacement for IMAPS/POP3S maybe it would be good to create a request on Feature Suggestions: Top (1832 ideas) – Your Ideas for Plesk

well, taking that literally, I'd remove support for unencrypted POP3/IMAP and keep POP3S/IMAPS.
Sending passwords over unencrypted connections is a huge security risk anyway, so the insurance companies aren't exactly wrong about this, they just could have worded that better ...
