Hi Guru,

I am wondering is there any illegal characters that I need to worried about or do something when I'm using sendmail to delivery an email?

In particular when/IF there is any illegal characters inside variable like $to_email, $from_email, $subject.

my $mailprogram = "/usr/sbin/sendmail -oi -t";
open (MAIL, "|$mailprogram") || ($errmsg = "Error $!");

print MAIL "To: $to_email\n";
print MAIL "From: $from_email\n";
print MAIL "Subject: $subject\n";

The $from_email may contain value like "Someone Name <$form_email>". The name is obtain from Form, therefore should I do any filter?
