[SATLUG] sendmail logging

[Leif Johnson]

I've tested my mailserver (sendmail-8.14.1-4.1.fc6) for open relay and the 
report says I'm not open. Fine. I have my /etc/mail/access file limited to 
relay from localhost only:

# by default we allow relaying from localhost...
localhost.localdomain           RELAY
localhost                       RELAY
127.0.0.1                       RELAY

Yet I keep seeing entries such as this in my maillog:

Sep  2 11:40:35 mobydick sendmail[26541]: l82GLnJe026541: lost input 
channel from [219.248.195.170] to MTA after data
Sep  2 11:40:35 mobydick sendmail[26541]: l82GLnJe026541: 
from=<alelu at pisem.net>, size=0, class=0, nrcpts=0, proto=ESMTP, 
daemon=MTA, relay=[219.248.195.170]
Sep  2 11:41:04 mobydick sendmail[26539]: l82GLn2v026539: lost input 
channel from [219.248.195.170] to MTA after data
Sep  2 11:41:04 mobydick sendmail[26539]: l82GLn2v026539: 
from=<kaluga at white-cat.com>, size=0, class=0, nrcpts=0, proto=ESMTP, 
daemon=MTA, relay=[219.248.195.170]

Can someone tell me if those are just bounces or does this indicate that 
my mailserver is being used as a relay of some sort?
