arc email authentication

Author: limodounbsp; I have previously written an article about how to use socket programming to send emails to solve the problem that web servers do not support the mail () function. It can also be used after my tests. However, at present, many free email providers (starting from 263, 163, and xinlang net) all add smtp functions.

The number of emails sent in the past few days is small.ProgramBy the way, I checked why SMTP mail servers such as 126 and Gmail cannot use the SMTP commands in the lab class to send emails. At that time, based on the returned information, I only knew that the server needed identity authentication. Today, I finally found out how to telnet to the SMTP server with identity authentication. Provide a base64

E-mail authentication is perhaps the most common form of Web page verification, which, in addition to verifying e-mail addresses, optionally checks the MX record in the DNS of the mail domain to make the message validation more powerful. function Is_valid_email ($email, $test _mx = False){if (eregi ("^" [_a-z0-9-]+) (. [ _a-z0-9-]+) *@ ([a-z0-9-]+) (. [ a-z0-9-]+) * (. [ a-z]{2,4}) $ ", $
