First let me explain what "Test Mail Server Tool" is
Test Mail Server Tool (http://www.toolheap.com/test-mail-server-tool/) is a small freeware application for having a testing mail server.
I installed Drupal 7 on wamp and then installed this Test Mail Server Tool, but am I not getting emails from drupal. However when I use the php mail() function in a plain php file, I get emails without any problem.
So my question is:
Does Drupal 7 uses the mail() function for sending email?
