pop3SecureSocket and Catalina

a user of an app of mine tells me that the app fails to get mail in Catalina 10.15.1.
Unfortunately I’m not yet ready to move from Mojave to Catalina, so I cannot test my app.

Anyway, is there somebody who experienced any problem using POP3SecureSocket on 10.15.1?



a) Get a second computer.
b) Install VMWare or Parallels.
c) Install Catalina on an external hard drive.
