"The DNS server received a bad TCP-based DNS message from 12.5.20.83.
DNS queries are UDP, not TCP. TCP is reserved for zone transfers.
The packet was rejected or ignored. The event data contains the DNS packet."
so no harm done, unless the bogus packets are coming in at DoS rate.
The IP is the machine that is only serving IMail.
I bet you have w2k dns running on that machine and don't realize it?
Imail should never send a DNS query over TCP.
