This happens when you use an old Postfix version AND have MIXED
line endings (some lines end in <LF>, other lines end in <CR><LF>).
Two solutions:
A) Use consistent line endings: ALL lines end in <LF>, or ALL lines
end in <CR><LF>.
B) Upgrade to a Postfix 2.9 or later that strips <CR><LF> regardless.
as described in the manpage entry below.

sendmail_fix_line_endings (default: always)
Controls how the Postfix sendmail command converts email message line
endings from <CR><LF> into UNIX format (<LF>).
always Always convert message lines ending in <CR><LF>. This setting is
the default with Postfix 2.9 and later.
strict Convert message lines ending in <CR><LF> only if the first input
line ends in <CR><LF>. This setting is backwards-compatible with
Postfix 2.8 and earlier.
never Never convert message lines ending in <CR><LF>. This setting
exists for completeness only.
This feature is available in Postfix 2.9 and later.
