Try disabling your anti virus from scanning outgoing email.

In the case of windows defender, it has no email scanner, try creating an exclusion for Thunderbird.exe. See https://support.microsoft.com/en-au/instantanswers/64495205-6ddb-4da1-8534-1aeaf64c0af8/add-an-exclusion-to-windows-defender-antivirus

But include the path to the file in program files as discussed in the next link as not doing so creates a big security hole. https://www.reddit.com/r/Windows10/comments/5gf38v/when_excluding_a_process_in_windows_defender_do_i/
