If I connect to the SMTP server with authentication on. (It is fine without any authentication.) If I turn it on I get the following problems.
Outlook:
If I select "use same setting as my incoming mail server" or "Log on using" with or without requrie SPA, I get the following message: "None of the authentication methods supported by this client are supported by your server".
If I choose 'Log on to the incoming mail server before sending mail" (which I have activated on the server), it works fine.
Iphone: I get "'mail.insureyoutoo.com' doesn't support Password authentication. Please check your account settings and try again."
Any thoughts on what is going on?
