Variables that control Email Sending
Simulate Sending of Email

$email_send_simulate_only = true;) to simulate email sends instead of really sending them through SMTP.

You will still be able to see the emails that would have been sent through the Emails > Sent tab in the back-office.
Allow PHP mail() Sending
Turn this off to prevent sending of emails if no external SMTP gateway is configured.
true and no SMTP gateway is configured, b2evolution will behave the same as with
$email_send_simulate_only = true;
