fast SMTP needed for my VPS

Hi Thank you for spending time to have a look on my project. I have a VPS server. It has a qmail smtp server. If we send emails the emails are in the queue only and not going to recipients. I want some body to work on the SMTP server and the emails should go properly. Even though for 30 emails they are in the queue and the queue is getting increasing to 1000. And i heard from somebody that we can get the reports of success/failure of emails to my email. Who can do this will be added advantage. Please pm me for further questions if you have any. Low budget wins the project. Thanks and Regards, Webmaster
