Reportedly, he base64 encodes his text.
I suspect there is some base64 DEcoder in the path that mistakenly
exposes his PC's <CR><LF> line breaks.
The Postfix SMTP server will strip <CR><CR><LF>, but the Postfix
sendmail command will strip <CR> from <CR><LF> only if the first
input line ends with <CR><LF>.
Fix: use quoted-printable for text, instead of base64.
