We use the barracuda spam/firewall and for the most part it works great. I have noticed over the last few weeks though that they are starting to use the server IPs instead of the MX records thus bypassing the spam filters. I have also noticed tons of attacks coming in over last week or so. Dfix seems to be catching tons, and by the end of the day I have 100s of Dfix blocks. _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
