PHP contact script send by SMTP?

[Garry]

Hi,

What is the best way have a PHP script to send a message by SMTP?

[Tony]

You'll need to create an email account to send from then since you're not using the mail() function then you're probably best to utilize a mailing library.  Here are a few examples of them:

http://swiftmailer.org/
https://github.com/PHPMailer/PHPMailer

 

If it's a third party application a lot of them already can interface with SMTP.  You just need to tell them the SMTP server and a username and password.
