Hi,
There have been some changes, so you may need to update your email settings on the device you are using.
Password encryption has been replaced with secure ports SSL/TLS for incoming and outgoing for your email address/device - settings on this link:

If you have an SPA tickbox you need to untick it or set Password authentication to Normal password. On ipad/iphone set SSL to on and use authentication password
Hope thats a help
