[cobalt-users] Help with semadmail logs

["Roger Smith" <rsmith@xxxxxxxxxxxxx>]

Is there a reference to help me decipher sendmail log entries?  I'm
trying to make sense out of entries that look like this pair:
 
Jan 30 11:40:30 mail sendmail[11670]: i0UJeNr11670:
from=<1-345046-metarainc.com
?rmXXX@xxxxxxxxxxxxxxxxxxxxxx>, size=8021, class=0, nrcpts=1,
msgid=<153$3E154n1T
sBEB4IMYMp1@xxxxxxxxxxxxxxxxxxxxxx>, proto=SMTP, daemon=MTA,
relay=sun4.rusticsu
nrise.com [66.111.234.26]
 
Jan 30 11:40:30 mail sendmail[11671]: i0UJeNr11670:
to=<rmXXX@xxxxxxxxxxxxx>, del
ay=00:00:01, xdelay=00:00:00, mailer=local, pri=37639, dsn=2.0.0,
stat=Sent
 
rmXXX is a valid user accessing the system from a remote location.  The
"relay" in the first entry bothers me.  I'm not aware of who the domain
is, but several such entries appear in the log with different domain
names, but very similar IP addresses (differing by only a few numbers is
the last octet).
 
Any help or direction to an information source would be appreciated.
