Even though mail has been intended as a decentralized system, there is more and more "corporate centralism" making it hard for independent users to run their own mail infrastructure, simply because the "big ones" deny accepting and delivering mail from sources they consider "spam" (while their own addresses will often be found origins of spam). A static IP is of course a very good help (and if you don't have one, using your ISP's mail relay "smart host" solves most problems), but if that IP is already on one of their black lists, it's hard to get it "approved" so you can operate normally. And it will probably happen again and again. Sadly, the "general public" (educated users) seem to have lost the ability to normally operate their mail servers, or more precisely: it has been taken away... :-( --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
