This is what I am seeing on the server syslog. Every half hour or so, I get two messages: smap[21550]: 205.240.25.2 host address lookup failed smap[21550]: connect host=unknown/205.240.25.2 This is the Pond's (pond.net) IP address. Apparently SMAP is trying to find out the domain name associated with the IP address, so it can determine if they are one of the sites that we don't want spamming us. This inverse DNS lookup is failing. I can test this inverse lookup with the nslookup program, which also fails for this address. All other addresses I try are successful. Any idea what might be causing this? Please e-mail me if you have a fix: tecsupport@uswest.net Thanks, Eric

Any idea what might be causing this? Because the ixa.net servers that this reverse domain is delegated to aren't responding to DNS queries (they respond to pings, though). -- Barry Margolin, barmar@genuity.net Genuity, Burlington, MA *** DON'T SEND TECHNICAL QUESTIONS DIRECTLY TO ME, post them to newsgroups.

Would this cause my problem and can it be fixed?

It can be fixed by the ixa.net system administrators. Check your Gauntlet documentation to find out if there's a way to make smap tolerant of client lookup failures. >"Barry Margolin" <barmar@genuity.net> wrote in message >news:zvM35.21$E45.648@burlma1-snr2... >> In article <cKA35.445$ZW5.35549@news.uswest.net>, >> TEC <tecsupport@uswest.net> wrote: >> >This is what I am seeing on the server syslog.
