Introducing mailbox Services in PHP, using third-party SMTP mail services

In the project, there is a time limit for SMS notification, which is insufficient for some information with large frequency. Sending information using a mailbox is a good choice \ (^o^)/!

First to register a mailbox, in the mailbox settings to open the SMTP function.

The simple introduction of SMTP, is probably the third-party client login mailbox function. With the SMTP feature turned on, the mailbox classes in our project can act as mailbox clients and send messages. (note, however, that the password will not be the login password for the mailbox.) The mailbox generates the authorization code or the authorization code you set.

Here's the dry goods
