[PHP] can php detect whether an email address is a valid one?

2001-11-13 Thread Alex Chau 

I have a php script sending newsletter to a mailing list time by time, 
but some emails are no longer exist, so I need to remove them manually.
Can php detect whether an email address is a valid one, then remove it 
from the list automatically? no matter before or after the newsletter 
has sent.

Thanks in advance.

You can set the Error-To:  header to some email address that runs a script
to remove the email address - other that that, no, not that I know of.

function checkmail ($mailtocheck) {
if (eregi(^[_\.0-9a-z-]+@([0-9a-z][-0-9a-z\.]+)\.([a-z]{2,3}$),
$mailtocheck, $check))
{
if (getmxrr($check[1]...$check[2],$temp))
