In IIS + PHP, modify the default sending mode of WordPress to SMTP (no plug-in)

1. modify the pluggable. php $ phpmailer-IsMail (); changed to $ phpmailer-IsSMTP (); 2. modify the entries var $ Mailersmtp; var $ Hostyoursmtpserver; var $ Port25; var $ SMTPSecure; var $ SMT under the class-phpmailer.php under the wp-schemdes directory

1. modify the pluggable. php $ phpmailer-IsMail (); changed to $ phpmailer-IsSMTP (); 2. modify the entries var $ Mailer = 'smtp '; var $ Host = 'your smtp Server'; var $ Port = 25; var $ SMTPSecure =; var $ SMT

1. Modify pluggable. php under wp-pair des.
$ Phpmailer-> IsMail ();
Change
$ Phpmailer-> IsSMTP ();

2. Modify the entries under the class-phpmailer.php under the wp-des directory
Var $ Mailer = 'smtp ';
Var $ Host = 'your smtp Server ';
Var $ Port = 25;
Var $ SMTPSecure = "";
Var $ SMTPAuth = true;
Var $ Username = 'your mail account ';
Var $ Password = 'your mail password ';

In addition, if anti-virus software, such as McAfee, is installed on the machine, php-cgi.exe is regarded as a worm. Therefore, you need to modify the protection rules:

The above method is actually to connect to the SMTP server through a Socket to send an email (verification method). If it is on the IIS + PHP + Discuz host, there is a graphical webpage setting page for mail settings, the operation is much easier.

Note: if you do not use the authentication method (that is, use anonymous SMTP to send emails), you can send internal emails, but not external emails, the cause of the failure is that the SMTP server password of IIS is not verified when the email is sent.
