How to set port and host for php function mail()

Question

I have set up a website at online domain, and the php mail() function is not working. The technician tells me i have to set the port = 2525 and host = mailout.one.com. Can someone tells me how to set the right port and host?

i'm not using xampp, thus php.ini does not exist

Thanks.

Answer 1

You can set it at runtime for testing. But if it works you'll want modify your php.ini file.
Put this at the top of your mailer script to test.

ini_set('SMTP','mailout.one.com' );
ini_set('smtp_port',2525);

To change it in your php.ini, you can just search for 'SMTP' or 'smtp_port'.
