Recently I find I cannot send any emails to Gmail addresses with Thunderbird. I can send to other addresses, and I can send to Gmail addresses using webmail. My emails to Gmails are refuse with:

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: 

boo@gmail.com
   host gmail-smtp-in.l.google.com [142.250.102.27]
   SMTP error from remote mail server after pipelined end of data:

I have spent hours on this but have not solved it. I recently installed Restoro software with CyberGhost and had some problems which were solved by adding VPN exceptions. However, even with these turned off (including VPN) the problem persists.

i cannot receive from Gmail addresses either.

In brief I can send emails from Thunderbird to any addresses except Gmails. I can not received emails from Gmail addresses either.
