No - that's SMTP which is a specific transport mechanism for email
(actually its a whole family of protocols but lets not go there) its
up to the MUA ('mail' command on Unix or the SMTP implementation
within PHP for |MSWin) to **convert** the message to a suitable format
for the MTA, which may in turn encode the message in a different
format depending on the carrier protocol.
Perhaps historically the SMTP implementation in PHP couldn't
accomodate this.
If you sniff the SMTP connection you'll see that long lines do get
wrapped - but the original message is restored when it comes out the
MUA at the other end.
