Is there still anybody who has problems posting? The problem was that one of the spam blacklists (the most wellknown) stopped working, and my server was trying to connect to it whenever an email arrived. This completely tied down the server. I am administering 8 computers here, and I fixed this problem on each 2 months ago when the problem started---except on the original (my first) one with the LyX lists on it.
Really sorry guys, Máté
