"Cannot Connect Using SSL: Thank you , but I dont believe I have any such software on my phone, I changed nothing and suddenly started getting the message it could not download mail and when I try to set up mail it now gives me the SSL message"

You are welcome.

Troubleshooting this:

• New App Password:

See what happens when you remove the address, and then add it back. If you were to add it back, you may need an App Password. Contact your eMail provider, if you are uncertain as how to do so.

• Another iOS Device:

Are you able to log in using another device? See if you get this error logging into it on another device - particularly an iOS device.

• VPN Connections:

Are you connecting to this on your own home network? If it is school or work that you are using, then a VPN may be what is being used here.

• Restore from a Backup:

Have any backups of this iPhone? If so, restore from it.

• Reset your Router:

Your Router would be setting this up, overruling connectivity.

SSL is Encryption:

You are getting this message because you are trying to connect using encryption. So, if connected to an encrypted (secure) connection, then disconnect from it. Such connections come from Security Software. So, remove Security Software from your iPhone. Simply, hold you finger in its icon, and click the "X" on the top-right corner of it.

"Thanks for all the suggestions, I was about to restore from a back up when all of a sudden it just started working - very strange - when I tried to log into webmail on my providers page I got a warning that the site was not secure and the certificate is not valid[...]"

Securing this:

So it has been restored, correct? You are getting this message, due to things being insecure. I recommend:

1. Updating: your Mac
2. Scanning: for Malware
3. Clearing: Temporary Internet Files:

In Depth:

A. Updating your Mac:

So, check for updates, update your Mac, and then restart it.

B. Scanning for Malware:

Start with running a scan for malware, using Malwarebytes for Mac and remove what is found. Perhaps something was installed that made this occur. Remove what is found from the quarantine. Malwarebytes is made by longtime users of these forums, and is the only security software safe to use on a Mac, as it does not get in the way. So, once removed from the quarantine, uninstall Malwarebytes, if desired.

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller

C. Clear Temporary Internet Files:

Boot into Safe Mode and then Clear your Temporary Internet Files of Safari:

• Booting into Safe Mode:

[hold down shift upon boot until the login screen appears]. See if this is still an issue. Safe Mode lets items run as default, without changes whatsoever. That is possible because caches of your macOS are temporarily disabled while in Safe Mode.

• Clearing your Temporary Internet Files (Cookies & Cache) of Safari:

Cookies perform remembrance of certain site-entered data. Whereas Cache keeps a snapshot of the last time you visited a site.  Use this Link: Clearing History and Cache - Apple Communities
