Ok, so it is documented for others. It appears that it is a "bug" in Thunderbird due to the windows PAC in the kerberos ticket. Assuming you have followed instructions elsewhere and userPrincipalName is set properly in the AD, make sure you have the right line_length_limit for postfix. If you are using dovecot sasl with postfix and are using Thunderbird in Windows (part of an AD domain) and using smtp kerberos authentication, make sure you have line_length_limit = 2176 in postfix's main.cf.
