How can I detect SMTP?

[bobleny]

How can I detect SMTP? I have a php script that wont send out an email, no errors, so I think the SMTP is disabled? I'm not sure how that part works. This script isn't for me, and I don't know if there server will have the capabilities to send php email. So, before I tell php to send the email, I want to see if it can send an email.

 

So I have a few questions:

1.) How can I detect SMTP settings?

2.) How do I enable or install SMTP?

3.) Is there a way to turn SMTP on from a PHP script?

[trq]

1) ini_get.

2) SMTP needs a mailserver. They are not a simple matter to install. However most isp's provide one you can use with your account.

3) See 2. Also, look at ini_set.

So I would check it like this? I don't know what to look for.

 

ini_get('SMTP')

[trq]

Did you read anything in the link I provided?

[bobleny]

Yes I did, and I see nothing about SMTP.

 

I know how to use the ini_get().

 

I don't know what to put in the "()".

Here, I made this and it doesn't work... I don't know what my ini file calls the SMTP thingy....

 

<?php
if (ini_get('SMTP') == TRUE && $set == "1")
{
$to = "[email protected]";
$subject = "Test";
$message = "This is a test message!";

if (mail($to, $subject, $message))
{
	echo "Sent";
}
else
{
	echo "Error!";
}
}
else
{
echo "Disabled";
}
?>

[trq]

echo ini_get("SMTP");

 

Will show you your current smtp settings. There is an appendix here that shows what can be set / seen from ini_set / ini_get.

[trq]

If ini_get displays localhost (default) you will need a webserver on your machine. Otherwise, you'll need to change the ini setting to reflect the mail server your isp or host provide you.

 

You really don't want to setup a mailserver unless you know what your doing.

How do I find out what the mail server address of my ISP is?
