using core php mail() to send via gmail SMTP

Question

Is it possible to send mail in core php via gmail smtp without using any external class?

Answer 1

I don't think it is possible because you need to perform an authentification. Also, you need to connect via an SSL socket, I don't know if the stock mail() function support this.

If you are willing to use the Pear Mail package, you might want to take a look at this:
