RE: [PHP] SMTP/mail question From: mailing_list <email protected>
Date: 06/22/01

Hi!

I did it!
once again what I wanted to do:
I wanted to send a mail, but use "MAIL FROM:" and "RCPT TO:" from the
SMTP-Protocol and check, if the domain is accepted (nslookup MX)!
I had a perl script, that does this trick. Unfortunately the php-mail()
can't do a "RCPT TO:" and "MAIL FROM:" explicitly (would be great in a future
release!!!) !

for them who don't know: 

--
telnet mymailserver 25
HELO localhost
MAIL FROM: realsender <email protected>
RCPT TO: realrecipient <email protected>
DATA
To: niceaddress <email protected>
From: niceaddress <email protected>
Subject: TESTMAIL

This is the Body ...
.
--
the result:
.) if address is correct: mail will be delivered to realrecipient <email protected>,
though in the To: header is written something else.
.) if there is no user realrecipient at you.com, the mail will be resent to
realsender <email protected> (Delivery-Error), though in the From: header is written
something else.
.) if the domain you.com doesn't exist or doesn't have a valid MX-entry,
then the RCPT TO: isn't accepted and the mail won't be sent!!!

what I did (my sendmail.pl handles 1.RCPT TO, MAIL FROM;2.Mail
Headers;3.Mail Body - all stored in $message):
$fh=popen("scripts/sendmail.pl","w");
fwrite($fh,$message);
if (pclose($fh)==0){
  echo "Mail was sent successful!";
}else{
  echo "Couldn't deliver mail (none or wrong MX-entry)!";
}
