Hello Zhang,

Does iRedmail provide any API, so that I can call it for sending an email from a PHP webpage ?

Currently I am using a phpmailer (http://sourceforge.net/projects/phpmailer/) that comes with the Simfatic Registration Form (https://github.com/simfatic/RegistrationForm).

It is successfully sending emails. But the problem is that the emails are going to the spam folder. The reasons may be:
1. phpmailer sends out emails without authenticating with the mail server.
2. The headers are not correct.

I have checked the header of the email arrived in the Spam folder. It doesn't have spf and dkim "pass". So I just thought of some iRedmail API that I can call instead of calling the phpmailer's API. Please suggest.

Header Follows
