About 2 3 weeks ago I suddenly started getting my emails to others that I have been emailing for years rejected. With the following msge.

Delivery has failed to these recipients or groups:

Maxwell, Mark [USA] (maxwell_mark@bah.com) 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. Generating server: PH0PR17MB5769.namprd17.prod.outlook.com

maxwell_mark@bah.com Remote Server returned '550 5.6.11 SMTPSEND.BareLinefeedsAreIllegal; message contains bare linefeeds, which cannot be sent via DATA and receiving system does not support BDAT'

Something in Thunderbird changed.

How do I correct this ????

Thx

I have seen several such issues, and all that I saw were related to the AVG antivirus that was inserting a line at bottom of emails. So, maybe not AVG, but something is adding an incorrect line to your emails.
