	But look at it again...

Oct 16 00:02:32 valhalla sm-mta[69570]: l9G42RKM069570: SYSERR(root): collect: I/O error on connection from dsl-189-133-2-240.prod-infinitum.com.mx, from=<roberto at geocities.com>
Oct 16 00:02:32 valhalla kernel: Oct 16 00:02:32 valhalla sm-mta[69570]: l9G42RKM069570: SYSERR(root): collect: I/O error on connection from dsl-189-133-2-240.prod-infinitum.com.mx, from=<roberto at geocities.com>

	I didn't wrap the lines this time. 

	Its the SAME message. Once normal, ONCE logged as "kernel". I would believe
something is KNOWINGLY outputting it twice. If it was 2 DIFFERENT messages, I
could see it was completely a lack of new line issue. But why would it log
the sm-mta output, then *something* part log a kernel message, THEN re-log
out the sm-mta message?

	I tried to tcpdump port 514 to see if I can see sendmail doing it, but
it looks like since its on the local machine it might be using syslogs char
special device.  How would I debug that (Short of running syslog in debug
mode)

		Thanks, Tuc
