For more info, you can ftp to > bruno.cs.colorado.edu, or telnet there and login as 'netfind'. I know netfind uses EXPN, so I doubt it does VRFY's, too. When I needed a quick and dirty method for checking smtp connections on SunOS, I saved time-stamped output from netstats that contained the string smtp. When the connections involved someone typing in commands, poling netstat once a minute caught them. Otherwise it took intervals of 4-5 seconds. Really quick, really dirty, really worked. -- Jeff Stehman Systems Staff, G-18A Jordan stehman@cs.clemson.edu Dept. of Computer Science (803)656-2639 Clemson University
