Why would this be showing then as the IP address for a majority of the outgoing email?
Not just mine but other customers originating from other physical locations?
it's tcp/ip protocol convention that the local loopback address and network is reserved for 127.0.0.1 and 127/8. "local" meaning it exists, by default, in each tcp/ip protocol stack.
eg: If some sets up up BIND on unix/windows but does not set an ACL to accept recursive queries from 127/8, then the "lcoal" machine's DNS queries will be refused, since the query's source IP is 127.0.0.1, same as what you see.
run
netstat -an
... to see the 127.0.0.1 as the listening address for some services.
I see intermittant log lines with this before 3/1/05 - after 3/1/05 there are an abundant number of them. (This is causing issues with Declude HiJack.)
now, WHY it changed in your experience is a different question.
