Mar  9 12:40:57 rbmain2 pop3-login: Login: rado [10.0.0.12]

as the mail log showed, it sent a msg to my hotmail account,
radopowder@xxxxxxxxxxxx I went to that account and replied to that msg.
...waited ample time for the msg to get back to rivers-bend.com and
never did. Now, while writing this msg, that reply shows up here on this
box. sigh

incidently, to make it even more confusing, I'm gonna duck when I tell
y'all this, but my ip connection is NOT bridged...but PPPoE, granted,
normally there is no static ips w/a PPPoE connection but seeing that my
ISP and I have been knowing each other and have been friends since
before dirt. As a friend deal, he just guarantees me that it will be
static. But really, this has nothing to do w/the problem at hand.

thx y'all
