Sorry if this is too off topic but I reconed you would feel my pain.

We are having major problems with our email at the moment and I would like to ask the help of the members here to track it down.
It appears that some of our mail arrives and some just disappears into a black hole. It seems to be related to the ISP of the sender but I cant gather enough data to prove it yet.

Can you send me an email at test@sambasoftware.com and make a short note here that you sent it. That way I can see how bad the problem is and how big a stick I need to use on the heads of my hosting company.

Thanks in advance. Charlie
