Looking for recommendation for a light-weight, SMTP server, with basic capabilities (will be run on port#25, with authentication but clear-channel), and it's use shall be limited to a particular (or a small set of) domain(s), i.e. mail to/from same set of domain(s) for authenticated members (both to/from fields) only shall be accepted, and of course, with additional spam filtering (bayesian possibly).

Target platform is Ubuntu Server (10.04.01) / CentOS 5.5.

TIA, ~i++

I also think postfix is a good solution for you. If you find you need an easy to manage spam filter solution take a look at this: http://assp.sourceforge.net/

If I were you I would use postfix, it's one of the most flexible SMTP servers on the market, with great guides all around the internet and a huge user base, you can't really go wrong with it, it also comes as a pre-packaged option both for Ubuntu Server and CentOS.

If you want to get a bit more advanced you can always go to sendmail, but considering your requirements postfix is a perfect fit.
