Suddenly I cannot send emails with Thunderbird to anyone with a gmail account.

I get a message: 

   host gmail-smtp-in.l.google.com [142.250.27.26]
   SMTP error from remote mail server after end of data:
   550-5.7.26 Your email has been blocked because the sender is unauthenticated.
   550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM.
   550-5.7.26
   550-5.7.26  Authentication results:
   550-5.7.26  DKIM = did not pass
   550-5.7.26  SPF [vincysurf.com] with ip: [84.116.50.179] = did not pass

I started to have this problem and get this message yesterday. All was OK before then.

Can you please assist.

Title should be:

"Cannot send emails to a gmail address"

Are you sending from an address belonging to a domain you own? Looks like your domain isn't configured properly to use SMTP authentication stuff (DKIM, SPF) meant to prevent abuse, and that's what's causing you to be blocked. This is something you'll have to solve at the website of your email provider. It may be as simple as figuring where those features are available and enable them, or you may need your email provider to help you solve the problem…
