Fix email encoding

The "From: " prefix size was not taken into accounts when
calculating how many characters were on the last header line
produced by mb_encode_mimeheader.

This is used to check if the e-mail address should be
placed on a separate line.

Fix the header separating character (needs to be \r\n).
Merge header creation with sendEmail.
