Send e-mail with socket (with SMTP server that needs to be validated) _php Foundation

?

* Name: send email with socket
* Description: This class implements the direct use of the SMTP server that needs to be authenticated to send mail directly, reference article "send email with socket" Author: Limodou
* This article is relatively early, he is using not to verify the SMTP server to send mail, now basically the SMTP server needs to verify, so this article in the class
The meaning is not very big! Also refer to [RFC 1869] and PHP manual!! And what's different is that I'm not using the Fsockopen () function
See for yourself!! I just passed the test, it's cool!!
In fact, this class can be rewritten to directly send the message with the attachment, look forward to ... I'll write it out for you in a few days!
I just debugging through, if you do not malicious to tease this program, he is still very obedient, after a few days I will be perfect for him plus the function of sending attachments!!

Even if your virtual host does not support mail functions, now you are not afraid! Come on, try this!

Please respect the success of other people's work, please retain this copyright information, thank you!
