Thanks for replying,  I take good note of the backend.php file.  I  
modified the config files as instructed.  After much investigating, I  
found that the issue was at Google's end.  None of my local  
applications could use my gmail account to authenticate (SAB,  
sendmail, etc) they are all throwing authentications errors or  
variants of such.

I wrote on google product forums, and theyre are tons of people with  
identical issues (Outlook, etc).

Today this is working as normal.  Google must have wrecked a setting  
somehow in our account settings.

That makes me question the choice of using Gmail as IMP's backend.   
What would be a more local (under my control) solution and still have  
IMP work with GMail for emails?
