RE: [cobalt-users] tailing logs across multiple servers

Don't bother ... use existing logging facilities.

Mail logging is done using the syslog facility.
Try "man syslog" and "man syslog.conf"

An "out of the box" RaQ 4 will have the following
entry in /etc/syslog.conf

# Log all the mail messages in one place
mail.*	/var/log/maillog

Assume you have 3 RaQ's, dopey, sleepy, and grumpy.
Add another line like this on dopey and sleepy ...

mail.*	/var/log/maillog
mail.*	@grumpy

Make syslogd see the change by sending a HUP signal to
syslogd.  Like this:

[root@raq4:/etc] # ps -ef|grep syslogd
root       298     1  0 Jun20 ?        00:00:08 syslogd -m 0
[root@raq4:/etc] # kill -SIGHUP 298

This will cause all mail messages to be sent to grumpy's
log also.  

Now you only have to look at grumpy's log to see all the 
systems mail logs.
