dedicated mail server

I'm trying to find the 'best' way to manage sending out emails.
Presently everything is going through an Exchange server but there are a lot of emails which get stuck in the queue.
There are several possible solutions but the jist of it is:
- have a dedicated mail server(Linux) and install software on it to handle mail sending/bounces etc
- use a web service such as constantcontact.com (if you know of any other decent ones, I'd like to hear your experiences with them)
- write the code in-house (a last a resort)

I lean toward the first option so we'd be able to manage it here... but, are there any good open source or commerical packages available (or have any suggestions)?
