What if my ISP's IP is black listed? I use blacklists on my mail server (http://www.spamhaus.org/zen/)
The failure delivery reports clearly state my ISP's address as being listed and indeed when I check on the blacklist, voila it's there. I have engaged my ISP on this issue but they seem reluctant to clean it up. However much they try delisting, it only takes a few seconds for the IP to appear again On Jul 27, 2012, at 4:02 PM, Emmanuel Sekyewa <[email protected]> wrote: > Hi, > > Try running wireshark or any other such tool on a machine on your LAN and > monitor traffic on your network for a while.
