Version 1.1.6 update required password to be re-entered then saved

It should work even if you don’t save it. But the password will be encoded only if you save it once.

Easy wp smtp From field now overrides From field set in Contact Form 7 settings.

Many users were having issues with receiving emails. So I changed it back to how it was in version 1.1.1

I think you will find that delivery issues in version 1.1.4 were caused by the incorrect email address being written to the Return-path: header.
In version 1.1.6 this has been corrected and easy smtp is writing the Return-path: correctly. (that is it is writing the smtp email address there)
Unfortunately 1.1.6 has another change that I consider unneccesary, with respect of making emails more deliverable. It forces a rewrite of the From: header.
This has the disadvantage of being less user friendly to the receiver of the email.
For the From: header I would prefer the Easy WP SMTP settings value only be used if the From: header has not already been written.
