Emails sent out to SMTP seem to go out, all settings, ports, ok... but my ISP (SMTP server) doesnt seem to receive it. It goes into SENT folder ok, shows being sent... but the SMTP server doesnt get anything. Using other email clients, SMTP works well there, same settings, web mails are ok. THUNDERBIRD ISNT. Please help.. I am on the latest THB 52.7.0 On Win7PRO, firewall clear... it suddenly stopped working 3 days ago. NO other updates, installs, changes. No automatic updates are on.

I suggest you log the SMTP connection. https://wiki.mozilla.org/MailNews: Logging would be the logical next step as you say the SMTP server is getting nothing and you see no errors from Thunderbird.
