Since about Christmas 2019 I have not been able to send messages from macOS Mail but can receive messages. Shaw Webmail works normally. I can send to myself and receive it using Shaw Webmail and can receive the same message using macOS Mail. I just cannot send or reply to messages from macOS Mail. I have followed Shaw published instructions regarding server settings for macOS Mail without success. When I view properties in macOS Mail the correct settings for incoming and outgoing server settings are as published. However I keep getting the message that the server pop.shaw.ca port 995 timed out. It cannot verify my Shaw ID or password although they are the same as those used for Shaw Webmail.

What are the settings used by Webmail?
