mail function does not work correctly with PHP 4.3.2

[socio]

Hi guys,
I am a bit confused.

I'm working to a PHP mail sender script, but i got in trouble with PHP 4.3.2 and Win2k.
I discovered that my old script (working good with PHP 4.1.2 and Win NT4) after passing to Win 2k and PHP 4.3.2 seems not to connect to mail server.

Below is what i submit to mail function in myscript:

<?

...

$mailstatus = mail('[e-mail]', 'Mail Subject', 'Some piece of mail body ...', 'From: [e-mail]');
return $mailstatus;

...

?>

The rows above work good in PHP 4.1.2 and returned $mailstatus value is 1, but with PHP 4.2.3 i got this error message:

<b>Warning:</b> Failed to connect to mailserver
verify your "SMTP" setting in php.ini.

In the real script i pass mail arguments by reference. I argued that the error woul have been in that, but I tried to pass them by values with no success.

I checked two php.ini files (version 4.1.2 and 4.3.2) for differences but i didn't find anything wrong:

SMTP = mymailserver.mydomain.com for all
Register_globas = Off in both files
sendmail_from = [e-mail] that is a registered account of our mail server

Anyone can answer me?

Try setting the smpt server and sendmail_from in your script.

ini_set("SMTP","server.name.or.address");
ini_set("sendmail_from","user@host");

I was an Idiot

I check all but ... firewall settings!
PHP 4.3.2 server was running behind a firewall that automatically disabled all programs which tried to use SMTP port but only mail client.

After disabling firewall settings all began to work good.

Sorry and thanks to all.
