MINOR: mailers: use <CRLF> for all line endings

Not doing so causes issues with Exchange2013 not processing the message
body from the email. Specification seems to specify that as correct
behavior : https://www.ietf.org/rfc/rfc2821.txt # 2.3.7 Lines

 > SMTP client implementations MUST NOT transmit "bare" "CR" or "LF" characters.

This patch should be backported to 1.6.
