The mail function does not allow you to send emails as needed, next, let's take a look at the smtp mail class and the solution to the problem.

When you are still struggling with the php built-in mail () function that cannot send emails, you are lucky now. This article will help you!

Php's use of the smtp class to send mails has been a trial. I have been using it for a long time and have never encountered any problems. In the background of this blog, when the blogger replies to a message, it will automatically send an email with a new reply prompt to the netizen. this method is also implemented in this article.

The smtp method for sending emails is actually very simple and stable. the class is already written by someone else. you only need to call it. A few lines of simple configuration can be used to send emails. are you looking forward to a try!

The email. class. php file has the following code:

 Debug = FALSE; $ this-> smtp_port = $ smtp_port; $ this-> relay_host = $ relay_host; $ this-> time_out = 30; // is used in fsockopen () // $ this-> auth = $ auth; // auth $ this-> user = $ user; $ this-> pass = $ pass; // $ this-> host_name = "localhost"; // is used in HELO command $ this-> log_file = ""; $ this-> sock = FALSE ;} /* Main Function */function sendmail ($ to, $ from, $ subject = "", $ body = "", $ mailtype, $ cc = "", $ Bcc = "", $ additional_headers = "") {$ mail_from = $ this-> get_address ($ this-> strip_comment ($ from )); $ body = ereg_replace ("(^ | (rn ))(.), "1.3", $ body); $ header = "MIME-Version: 1.0rn"; if ($ mailtype = "HTML") {$ header. = "Content-Type: text/htmlrn";} $ header. = ":". $.

The code for sending the php file of the mailbox is as follows:

 Debug = false; // whether to display the sent debugging information $ state = $ smtp-> sendmail ($ smtpemailto, $ smtpusermail, $ mailtitle, $ mailcontent, $ mailtype); echo"
"; If ($ state =" ") {echo" Sorry, email sending failed! Check whether the email address is entered incorrectly. "; Echo" Click here to return "; exit ();} echo" Congratulations! Email sent !! "; Echo" Click here to return "; echo"
";?>

Smtp class can not send mail solution, accidentally found that my website background automatic mail function is not available, this error is reported:

Trying to smtp.126.com: 25 Error: Cannot connenct to relay host smtp.126.com Error: () Error: Cannot send email to web@daixiaorui.com state

Cannot connenct relay host smtp.126.com error :() error: unable to send email to web@daixiaorui.com

After finding n more information on the Internet, I finally found a solution, not an smtp class problem, but a linux configuration problem. It turns out that the fsockopen function is disabled in php. ini of the server.

Open the php. ini file in the space. generally, php. ini can be customized in linux space. Therefore, this file is usually stored in the root directory.

This function may be disabled in two places:

1. allow_url_fopen = On to check whether the value is ON after allow_url_fopen = On. if the value is OFF, the function will be disabled.

2. disable_functions = fsockopen pfsockopen (this is my case) here we should remove the previous "fsockopen ". To make it: disable_functions = pfsockopen

After modification, save the email and refresh the page again. in linux, you can use the smtp class to send emails. Thanks for sharing the solution, and the problem has finally been solved.
