Optus instructions for setting up an email client are here:
It says: "From the 'Security Settings' options: Select 'None'"
And then, it says to send 'normal', that is, not encrypted password.
That's crazy! I am so not going to send my uncrypted password across the internet. There are bad people out there.
How do I securely connect to my email?
I don't think they offer it. You do have an encrypted connection via web mail I believe. I'm still surprised that folks still use ISP supplied email addy as there main stream.
