Warning: mail(): SMTP server response: 501 5.5.4 Invalid Address

my SMTP settings are as follows:

[mail function]
; For Win32 only.
SMTP = localhost ; for Win32 only
sendmail_from= vwar@synapticshock.org ; for Win32 only

Im running IIS, not apache

do you have an SMTP server running on 'localhost' ?

try your mail function with the to and from coming from you.
Also if you are on a company network try editing you SMTP address to be the same as your email server.

What is the email address you are sending to in $row['email']?

Is it valid?

A-im not to familiar with phpmail, so forgive me if i cant understand. from and to,im unfamiliar with. the SMTP server address is also localhost :)

Q-What is the email address you are sending to in $row['email']? Is it valid?
A-all the email address are valid, they are coming from an mysql database, ive tested these via normal mail thru the smtp server, and the smtp server works

The behaviour of these functions is affected by settings in php.ini.

Name Default Changeable
SMTP "localhost" PHP_INI_ALL
smtp_port "25" PHP_INI_ALL
sendmail_from NULL PHP_INI_ALL
sendmail_path DEFAULT_SENDMAIL_PATH PHP_INI_SYSTEM

When I send email on a windows platform, I don't use a local SMTP server. Instead I send the email directly to the recipients server, just like an SMTP relay server.

Here is the code.

<?php

function sendMail($sEmailToSend, $sSubject, $sMessage, $sHeaders)
{
$sGatewayIP = '10.0.0.1';
preg_match("'\.*@(.*)'sim",$sEmailToSend,$aMatches);
$sNSLookup = shell_exec("nslookup -q=mx {$aMatches[1]} {$sGatewayIP} 2>nul");
preg_match_all("'^.*MX preference = (\d{1,10}), mail exchanger = (.*)$'simU",$sNSLookup,$aMXMatches);
ini_set('SMTP',$aMXMatches[2][0]);
return @mail($sEmailToSend, $sSubject, $sMessage, $sHeaders);
}
?>

The only piece of information I am unable to determine automatically is the Gateway IP.

What I did to find this initially is ...

tracert www.experts-exchage.com

And the first address in the list is my gateway, and as I am behind a gateway/proxy, this is the proxy server's address.

What this script does is :

1 - Extract the domain name for the recipient.
2 - Runs NSLookup (a windows console app) to get the MX (Mail exchanger) records.
3 - Extracts from the first MX record the mail server's address.
4 - Sets the SMTP ini setting to this server.
5 - Sends the message.

From what I can tell, this will work EXACTLY as if you had telnetted into the recipients server and sent them the email. And as far as I can tell, this is pretty much what happens when you send an email to your SMTP server which then sends it to their server.

So should always work.

Now, the sharp eyes amongst you may be thinking why am I not using the PHP function ...

getmxrr() --  Get MX records corresponding to a given Internet host name.

Well, because I am on Windows and ...

"Note: This function is not implemented on Windows platforms. Try the PEAR class Net_DNS."

And I've not yet used the PEAR class.

Hope this helps.

Richard.

Thanks for the information, except it doesnt have anyting to help a Windows server

Unfortuantly im not to clued up on PHP sendmail, so ill tried to understand, but unfortunatly no sense came of it :(

If you do a

echo $row["email"];

before the "mail($row["email"],$subject,$temptext,$header);" line in your php script what does it return?

it returned an email address, which is correct

but this is the error im getting atm

Warning: mail(): Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in

E:\synapticshock.org\vwar\includes\functions_admin.php on line 574

looks to me that php mail doesnt want to connect to the SMTP server

the SMTP server is on the same box (localhost) and its def port 25

Yea, definetly sounds like it is having problems connecting to your SMTP server. Are you sure your mail server is working correctly and the security settings on the mail server are set up correctly?

well im having no probs with some forums using the SMTP server and the mail is def sending, as im using my friends on 4 dif ISPs to check

im pretty sure the security settings are correct

eg relaying for only local host, etc

any other ideas?

Ok, a few other things we can try
Make sure you have "sendmail_from=" in the php.ini filled out.

Try changing the "SMTP= " in the php.ini to 127.0.0.1 or your actual ip address.

Warning: mail(): SMTP server response: 501 5.5.4 Invalid Address in E:\synapticshock.org\vwar\includes\functions_admin.php on line 572

i changed it to the SMTP IP address

still no luck, anyone else can help?
