# This function will SAFELY send e-mail (ie you can pass parameters to it
# that you got from a form and not worry about header injection.) Weird
# characters are stripped from the $subject and from the real names, but e-mail
-# addresses are not modified at all. If an e-mail address is invalid this
-# function will return non-zero.
+# addresses are not modified at all.

+# RETURN values:
+# 0: e-mail successfully accepted for delivery
+# 1: badly formatted "from" address
+# 2: badly formatted "to" address
+# 5: message rejected by mail() (reason unknown)
# You cannot pass more than one address to any parameter
# address fields (from, to, cc, bcc) can be in either of these formats:
if($to == '') { return 2; }
#FIXME should allow many more characters here
