Email not received - If PHP mail() returns true, was mail sent ?

I would like to ask, if PHP email() returns true, does it mean email was sent ? Beacuse I am not receiving it.

Hi,

If PHP mail() function returns TRUE, it means email was created and accepted for delivery, but not automatically sent to recipient.

These are the possible problems:

• Sending of emails is not allowed or configured in php.ini
• Sending of emails is limited, not allowed or not configured at the level of SMTP server
• Email was successfully sent, but recipient's server recognizes it as a spam (because of IP address, email address or previous user actions)
