// The bug occurs on Unix systems where mail() function passes email to a variation of
// sendmail command which expects only NL as line endings (POSIX). Since quoted-printable
// requires CRLF some of those commands convert LF to CRLF which can break the email body
// because it already (correctly) uses CRLF. Such CRLF then (wrongly) becomes CRCRLF.
