When I run my web application which sends mail on my dev machine, the mail is not sent. The mail.info file shows that there was a host name lookup failure. How do i fix it? (i am trying to send mail to my gmail account.)

Looks like there is something wrong with your server's dns settings or sendmail itself if it has separate dns settings. Make sure they are valid and alive.
