FreeBSD VMail Howto
 

Im looking for a good howto for setting up a postfix vmail server using mysql. Google is only giving me Linux tutorials. Right now im look at this one: http://howtoforge.com/virtual_postfi..._quota_courier
Would this tutorial work for a FreeBSD system? Is there anything different I would have to do?

Anyone have a clue?

You should try it. Install all the things it lists (using ports). The start with the MySQL part (step 3). I've vgrep'd it and it seems reasonably correct to me. I don't currently do that but I can't see anything which screams out warnings.
