&gt; I found suspicious reports in the last few 'logwatch' reports on my 
&gt; RH-7.3 setup. The latest couple say:

&gt; I've been seeing those &quot;doing -bs&quot; lines since setting up my mail service, 
&gt; but I can't account for those massive numbers of messages.
&gt; 
&gt; Coincidentally(?), I no longer see those bogus attempts at SSH logins 
&gt; from scripts that try all manner of ususal accounts and passwords.
&gt; 
&gt; I'm running 'sendmail-8.11.6-23.73' from the RH rpms, and use 
&gt; 'fetchmail-5.9.0-21.7.3' to collect mail from my ISP's POP server.
&gt; 
&gt; What should I look for in /var/log/maillog (or elsewhere) to track this 
&gt; down?
&gt; 
&gt; TIA.
