dualfroz 709e2d5b62 Normalise line breaks in S/MIME signed messages 
openssl_pkcs7_sign() returns its headers and body with bare LF line
breaks. They were copied into the message verbatim, so signed mail was
rejected by SMTP servers that enforce RFC 5321 line endings with
550 5.6.11 SMTPSEND.BareLinefeedsAreIllegal.

Fixes #3067
