Hi Nick,

I will have a look at this and try some settings, especially the ones regarding RBL lists.

As i already said; a lot of the spam is already blocked. I almost receive none.

The ones that are coming through now are only from this week and affect 2 users on the mail server, one of them being me :-(
probably one of the reasons that they are hard to identify is that they are in my native laguage and are pretty well written.
