Why Isn\'t My PHP mail() Function Working on My Live Server?

Troubleshooting PHP Mail Function Failures

Q: Why is PHP mail() function not working on my live website?

A: Several factors can contribute to this issue. One common cause is the absence of the sendmail executable.

Recommended Solution:

• Navigate to your server's terminal and install sendmail using the command:

sudo apt-get install sendmail

• Reload the PHP page where the mail() function is called.

Additional Considerations:

• To confirm email delivery, check the spam folder of the recipient.
• Ensure your sendmail configuration is correct by running the following command in the terminal:

/usr/sbin/sendmail -bv [email address]

If you observe a response starting with "250 Ok", the configuration is valid.
