I received an email from UPC advising that only encrypted access will be allowed for email from October 31.
The link page is:
https://support-en.upc.ch/app/faq/a_id/22/setting-up-an-e-mail-account
But this shows the settings I have been using for over 20 years!
What, if anything, do I need to change?
