How to properly use the PHP Swift time-limit email relaxation function

We know that

PHP Swift code example for sending emails:

1. <? Php
2. Include_once ("Swift. php ");
3. Include_once ("Swift/Connection/SMTP. php ");
4. Include_once ("Swift/Authenticator/LOGIN. php ");
5. // Recipient's address
6. $ Receive_mail = "demo_receive@gmail.com ";
7. // Create an smtp connection. The smtp address and port used to send emails
8. $ Smtp = new Swift_Connection_SMTP
   ('Smtp .sina.com ', 25 );
9. // Set the email account used to send emails
10. $ Smtp-> setUsername ('demo _ send@sina.com ');
11. // Set the logon password of the sender's email address
12. $ Smtp-> setPassword ('1qaz2wsx ');
13. // Add ssl connection support. If this option is not enabled, it is sent to gmail.
    If this option is enabled, the mailbox that requires an ssl connection will fail.
    The email sending speed will be affected.
14. If (stripos ($ receive_mail, "@ gmail.com ")! = False ){
15. $ Smtp-> attachAuthenticator (new
    Swift_Authenticator_LOGIN ());
16. }
17. $ Swift = new Swift ($ smtp );
18. // Mail title
19. $ Title = "you have received a new resume for applying for a job as a php programmer ";
20. // Body of the email
21. $ Content = "Postmaster, hello! You have received a new resume,
    Apply for a job as a php programmer... <br/> ";
22. $ Message = new Swift_Message
    ($ Title, $ content, 'text/html ', 'base64 ');
23. Echo ($ swift-> send ($ message,
    $ Receive_mail, new Swift_Address
    ('Demo _ send@sina.com ', 'demo _ sender ')))
    ? 'Success': 'failed ';
24. ?>

We hope that the above PHP Swift usage will be helpful to friends who need it.
