[php-list] Plain text email

[Bob]

Hi,
I'm wanting to protect all inputs for sending a plain text email, in a common 
routine.

Have just found POSIX [:print:] which I thought looked useful.
I didn't want to use htmlentities(); because it's a plain text email.

Would this protect me from anyone sending spam though this?

$raw = stripslashes($raw);
$raw = preg_replace("/(content-type|bcc:|cc:|onload|onclick)/i", "DELETED", 
$raw);
$raw = strip_tags($raw);
$raw = preg_replace("/[^[:print:]]/", " ", $raw);
$raw = substr($raw, 0, 500);
$raw = trim($raw);

Or, should I use:
$raw = htmlentities($raw, ENT_NOQUOTES);

The email address would obviously be different.
This would cover just the name, subject and message.
I don't need newlines etc.

Thanks, Bob Exton.
