Drupal site can use Gmail mailbox to send mail to users, the implementation of similar functions have SMTP or Phpmailer module, I use the Phpmailer module, the following is the process of my configuration, posted for your reference.
1. Download Phpmailer module
Http://drupal.org/project/phpmailer
2, enable the Phpmailer module, in the "Site Settings" point "Phpmailer" settings, the page will be error "Class ' Phpmailer ' not found in .... Phpmailer.class.inc".
Why is it? The original Phpmailer module also needs class.phpmailer.php class.smtp.php
Open the Phpmailer module under the Phpmailer folder, the folder has a COPYHERE.txt, open can read a word:
Copy the downloaded files class.phpmailer.php class.smtp.php into this directory.
So when installing the module, you need to carefully read the documentation in the module to reduce the chance of error.
The above two files can go to the following link to download:
http://sourceforge.net/projects/phpmailer/files/
3, OK, download the above required files, you can go to configure the Phpmailer
