hi
we have a box facing the net that all our mail is routed through. we use the box to scan for viruses. my problem is that someone is telneting into that box and using it to send spam. our exchange server doesnt relay but since the mail is spoofed as a known address on the network it gets through. anyone had this prob before? i dont know how to stop the person telneting onto the box at port 25.
hope ive made some sense. any ideas?
cheers
