Early in 2018, around the time when I upgraded my system to Windows 10, the Stunnel and Blat files that had worked fine with my Vista PC would not work with the new PC. However, the "bug" turned out to be unrelated to the change in operating systems, but rather an "upgrade" to Gmail: Coincidentally, about that time, Gmail evidently decided to stop accepting e-mails from apps deemed "a less secure app", including Stunnel-Blat, with Blat then displaying messages:
*** Warning *** The SMTP server did not accept Auth PLAIN value. *** Warning *** Are your login userid and password correct? *** Warning *** The SMTP server did not accept Auth LOGIN PASSWD value.
Only a failure message sent to my "backup e-mail address" led me to explore this as a possible cause for what I had thought was, but turned out not to be, a Stunnel-Blat problem. Gmail has an option to suppress this heightened security feature, and when I activated this option, my Stunnel-Blat tools immediately began to function as intended.
While I was at first able to enable Gmail to "Allow access from "less secure accounts," I have been unable to get through Gmail options consistently to turn this on and off and share this info with others. (I would welcome instructions that work consistently.)
I would also welcome guidance on how to include Stunnel-Blat as a specific alllowed app, without having to enable Gmail to enable *all* "less secure apps"

Hi,
Click on your avatar, then Google Account, then Sign-In & Security. At the bottom of the page, there's "Allow less secure apps".
You can't choose which app is a less secure app, because this option may be understood as "re-enabling Basic Authentication" which means "plain-text password authentication".
By default, Gmail only allows Oauth authentication.
Regards, Flo

Yeah, well, wouldn't it be nice if only we had a system that would allow us to grant (possibly limited) access to specific applications by, say, issuing them a little authentication something that they could present to the authorities... we might even call it a "ticket"... but of course, not everything with access should be able to issue tickets, so we may have a ticket-granting ticket and a normal access ticket...
...yeah, wouldn't it be nice...
