Email won't send since downloading new version. I've checked all SMTP settings and they are correct. IMAP settings are correct as well. What's going on? I get the following error message:

Sending of the message failed. An error occurred while sending mail: Unable to establish a secure link with Outgoing server (SMTP) iris.nau.edu using STARTTLS since it doesn't advertise that feature. Switch off STARTTLS for that server or contact your service provider.

I do use a VPN, but even when off, I still can't send email.
