SMTP server on debian 6.0 linux

I have some questions: I am using a SMTP service for sending monthly newsletter for my website (~3000 email addresses).
I was thinking: I already own a virtual server configured as a web server and secured, why not using it to send email and save 7€/month ??

Is this a reasonable idea or am I a fool?
Does anybody knows a good (and up-to-date) guide for debian squeeze linux? I have read the official documentation, but i’ve understood a little…

And again: what I’m talking about is the so-called “smtp-relay”?

Setting up a mailserver on Debian can be quite annoying. I hope you have a few days/weeks. I suggest starting with something easier.

If you want a decent guide about how to setup a mailserver, I learned it with this one: http://workaround.org/ispmail/squeeze

Which is a very comprehensive guide explaining everything step by step. I you want mailinglists you can set these up with either of these:

• mailman
• sympa (bad documented though)
• mlmmj
