Hello, in last 2 days I experience this error, when trying to send e-mail using Thunderbird. 'The mail client submitted this message with bare line feeds, which cannot be sent via SMTP protocol DATA command and receiving system does not support BDAT. ' I was searching for a fix on Thunderbird, but found no solution. Microsoft explains what the error is about, but it does not solve. Sending out e-mails. Can somebody help, please? Sending e-mails works fine in windows 11 mail, not Thunderbird 102.1.2 64 bit. Thank you for any findings, suggestions.
