Hi all, 

I'm quite new to Drupal and started working with Drupal 7.

My development environment is Ubuntu 11.10 64 bit platform

I created an admin user and now i need to let other external users to register in my web site.

When a user tries to register, it asked for the email address, and when submit the message appears as the mail has been sent to the provided address.

But when I checked in the inbox its not there. I have installed SMTP Authentication Support module as well, and its in active state.

I guess Ubuntu comes default with a mail server running in port 25, so in SMTP Authentication Support config page i have given parameters as follows
     SMTP Server : localhost
     SMTP port : 25
     Use encrypted protocol : No

And when i send a test mail, it also says the mail has been sent successfully but it cannot be found in the mail (not in the spam even)


Please help 
Thanks in advance
