To send e-mails to your users in the registration or to make mailing lists of important news you should:

1. Create a mailbox on your domain. 

2. Write a script that will send e-mails. For example:

$to = '[email protected]'; Who receives

$subject = 'test'; E-mail thread

$message = 'hello'; Message

$headers = 'From: [email protected]' . "\r\n" .   Who sends.

IMPORTANT: You should write your mail account from which mail will be sent in the field “WWW domains” – Administrator’s e-mail and also indicate the way through Sendmail (sendmail_path = “/usr/sbin/sendmail -t -i -f [email protected]”) in the file php.ini (folder php-bin) to assure your script working.
