Hello there carlitosclassicab We have read your message. We try to help you.

You cannot send messages ?

What is happening when you cannot send them? How do you mean ccc.system? Ccc.exe?

Hello there again.

The problem suddenly started after updating to Thunderbird version 78? If your existing configuration suddenly stopped working after updating to Thunderbird 78, it might be your Antivirus or Firewall blocking the new version, or your email provider using outdated TLS security protocols. See these sections below:
