I'm using PHP version 4.4.3.

The manual page for PHP's mail() function (URL below) says that for the
message (IE. email body) "Each line should be separated with a LF (\n).
Lines should not be larger than 70 characters."

http://uk2.php.net/manual/en/function.mail.php

To see what happened I just sent an email using mail() with one of its
lines exactly 100 chars. It was sent perfectly by sendmail as a line of
100 chars and no newline. PHP did not seem to mind at all.

Why the limitation of <= 70 chars per line, and why does my version of PHP
not seem to care?

Thanks all.
