PHP under the use of Phpmailer with QQ mailbox under the domain name mailbox to send mail

As a developer of PHP, there is often a need to add a Web site that uses its own domain name as the sender's e-mail address to automatically send messages, for example, to send users a verification code, notification information, and so on. For example: One of my users to register the module, you need to use [email protected] as the sender of the mail to the registered user to send a message containing the account activation link in HTML format, the validation of the user registration account is filled in the mailbox is the person's own.

So, how is this method of using your own domain name as the e-mail address for sending e-mails under PHP?

PHP environment, is to provide the mail to send the function mail (), but the function requires the server to support SendMail or must set up a mail sending server that does not need to relay, but now to find a message that does not require authentication to send relay is almost impossible, Therefore, using the mail function often fails to send e-mail successfully. So is PHP unable to send mail? The answer is no, if you are familiar with the POP3/SMTP protocol, combined with the socket function can write efficient and stable mail sender, but this workaround is equivalent to using PHP to write a POP3/SMTP client, for the general user is still difficult.

Fortunately, there are so many resources on the Internet that it is not phpmailer to be greeted.

What are the advantages of Phpmailer?

• Can be run on top of any platform
• Support for SMTP authentication
• Specify multiple recipients, CC address, send address and reply address when sending mail; Note: Add cc, BCC only under the win platform SMTP mode support
• Supports multiple message encodings including: 8bit,base64,binary and Quoted-printable
• Support for redundant SMTP servers, that is, you can specify the primary SMTP server address and can only specify the backup SMTP server
• Support for mail with attachments, you can add any format of attachments to the message---of course your server has enough bandwidth support
• Custom message header information, which is similar to sending header information in PHP via the header function
• Support to make the message body HTML content, you can insert a picture in the body of the message
• Flexible Debug Support
• Tested and compatible SMTP servers include: Sendmail,qmail,postfix,imail,exchange, etc.

How do I download the Phpmailer code package?

Phpmailer Project Address: Https://github.com/PHPMailer/PHPMailer clone to local using git command, or click "Download ZIP" directly at the bottom right of the project page To get to the full Phpmailer code package.

How to use Phpmailer with the "domain Mailbox" under the QQ mailbox to use your own domain name as email address to send mail?

====

The following two parts, explain the use of their own domain name free to open the "domain Mailbox" under the QQ Mailbox and PHP environment using Phpmailer and with the newly opened "Domain name mailbox" Automatically send mail.

====

The first part: opening the "domain Mailbox" under the QQ mailbox

Since the opening of the "domain Mailbox" is only an understanding of how to operate, this part is only a brief talk.

• Enter the QQ mailbox, click on the top left of the page "settings", and then click on the "Mailbox settings" under the "Account" tab, drag the scroll bar, you can see the "Domain Mailbox", click "Manage Domain Name mailbox" To enter the domain name mailbox added pages, or directly click http://domain.mail.qq.com/
• Click "Create a Domain name mailbox" and follow the page prompts to add your own domain name and verify it. PS: If your QQ mailbox successfully added a "Domain name mailbox", then enter the QQ mailbox, the top left of the page "settings" button will have "domain name mailbox" text
• Add your own email address for the domain name mailbox, click "Member Management" in the "domain Mailbox" approved by the audit, click "Add Member", enter the email name under your domain name, then add QQ number (the QQ number is used as the user of the newly added mailbox. QQ is required to open the QQ mailbox and does not close the digital account number)
• Just entered the QQ number of QQ mailbox will receive an open domain mailbox notification mail, in the mail click "Accept this mailbox account", the use of phpmailer Send mail sender email address is set to complete, in order to facilitate the description of this email address called "Sender mailbox."
• For the QQ number of password security, please set the "Independent password" for the QQ, in the QQ mailbox "set"-"account"-"account security" to set up the password, in order to facilitate the description of this article, called "Independent password."

At this point, the "domain Mailbox" under the QQ mailbox is opened and added to the email address that will be sent as the sender using Phpmailer. Here are a few key information to be used by Phpmailer: QQ number, QQ number added in the third step above, "Independent password", "Sender Mailbox", Sender's name ...

Part II: Writing code to send mailboxes using Phpmailer

Phpmailer need PHP Socket extension support, and Phpmailer link QQ domain name mailbox need SSL encryption Method (QQ mailbox has recently limited, new open domain mailbox no longer allow 25 port through the SMTP protocol of the normal link way link, Only allow SSL 465 or 587 ports [I have a domain mailbox open in the domain mailbox currently 25 port is still can link, may be security policy, limit the new open domain mailbox account 25 Port ]), solid PHP also has the support of OpenSSL, Can view phpinfo, the following two items are available, including the OpenSSL version number, such as no tube; many web hosting PHP does not support OpenSSL extension, then you may be tragic.

This section is for code examples only, and some comments are explained in the code.

Download the Phpmailer after decompression to thin body, only need class.phpmailer.php, class.pop3.php, class.smtp.php and phpmailerautoload.php four files, language folder can not be, that is mainly used for debug debugging display information. Look at the file size of class.phpmailer.php, 110kb, quite scary.

Special Note: The above code snippet is for reference only, in order to integrate into the site system, you can encapsulate the code snippet into a function or class library for invocation, and Phpmailer in the Win32 platform is supported by the addition of CC, Dark send. Because my server uses CentOS, not tested
