mail() function is not sending mail, this seem issue with sendmail. i need this fixed, I pay $5
Thanks but I am not interested in smtp can i get troubleshoot for mail() only?The PHP mail() can be pretty unreliable and that's why a lot of professionals don't bother with it. Instead opting for API-based email sending such as Mailgun and Sendgrid. You can also use SMTP sending through PHPMailer, which seems to be a bit more reliable, but can be slow as emails are often not send immediately depending on configuration.
