Sending of the message failed.
Been using Thunderbird for years. Today while trying to send an e-mail I get this: "Sending of the message failed. An error occurred while sending mail. The mail server responded: See http://pobox.com/~djb/docs/smtplf.html.. Please check the message and try again."
I read the link and I have no idea what that means.
Using Win 10 and Thunderbird 102.1.0 (64-bit)
Chosen solution
I also contacted my host and this was their response:
Recently, we received several reports for outgoing mail issues following a recent AVG or Avast antivirus update. If you are using either of these applications, or any other antivirus/firewall app on your computer, please disable them for a quick test.
Since disabling your antivirus program permanently is not recommended, you may try disabling the signature in the application. Instructions are available at:
