Are any of you at the LVLUG knowledgable with setting up a mail-server? Currently the BCLUG mail server is run at some guys house who is too busy to come to the meetings. Its sorta embarassing

. We have been trying for months to get a in-house mail-server for us but plans keep on falling apart. Brian K. or I could get one set up probably pretty easily. But the thing is, we wouldnt understand what exactly we did or how to better configure it.
So I was wondering if one or two of you who are knowledgable in setting up a mail-server would be willing to come down to BCLUG for a meeting or two and set one up for us and along the way teach us how to configure it correctly, make it not be an open relay, etc. Would this be possible?
