I have instrumented my iptables to log all DROP'ed packets. I have a huge plethora of packets dropped from these 3 IP addresses: 74.125.127.109 72.14.213.109 74.125.53.109 and all of them are from source port 995, which is the secure POP3 port used by Thunderbird. All 3 IP addresses belong to google. nslookup reports 109.127.125.74.in-addr.arpa name = pz-in-f109.1e100.net 109.213.14.72.in-addr.arpa name = pv-in-f109.1e100.net. 109.53.125.74.in-addr.arpa name = pw-in-f109.1e100.net I am having no problems retrieving my email at all. TB works just fine. All 3 addresses belong to google. Just do whois 1e100.net So why would the google mail server send me unsolicited packets? As I said, I am having no problems sending/receiving email.
