If you find that the port is also blocked, then the only solution is to contact your hosting provider to unblock these ports. When these ports are blocked, try to connect using port 2525.
This is true even for some of the dedicated servers. This block is been purposely done by your hosting provider. In case you are on a shared hosting server, ports 25 and 587 remain blocked by default. And, this can be easily traced at the server maillogs (the location of the server of mail log can vary from server to server, as explained above). Port block is a very common problem that most developers face while integrating their code to deliver emails using SMTP. Inside will be error messages the server reported, if any, related to your attempts to send emails. The location of these logs will vary (you may need to ask your server administrator where they are located) but they can commonly be found in a user's root directory under logs. Your web server should be logging all attempts to send emails through it. If your call to mail() does not have the correct parameters in the correct order it will also fail. If your call to mail() does not have at least three parameters it will fail. The mail function takes three required parameters and optionally a fourth and fifth one. Make sure the mail() function is called correctlyīool mail ( string $to, string $subject, string $message ] ) Make sure it is there and not commented out. It may seem silly but a common error is to forget to actually place the mail() function in your code. See How can I get useful error messages in PHP? - this answer for more details on this. Placing the following code at the top of your PHP files (or in a master configuration file) will enable error reporting. Error reporting needs to be enabled to receive these errors. Make sure error reporting is enabled and set to report all errorsĮrror reporting is essential to rooting out bugs in your code and general errors that PHP encounters.
Without one, you need to run through the checklist below to find any potential pitfalls you may be encountering. It's difficult to diagnose these things unless there is an obvious syntax error. There are a variety of reasons your script appears to not be sending emails. Although there are portions of this answer that apply only to the usage of the mail() function itself, many of these troubleshooting steps can be applied to any PHP mailing system.
