We're talking about an RS6000 > AIX box in case it matters. Since it's AIX, you're probably running Sendmail. Please note that as far as I know, the IBM-supplied Sendmail will *not* do probes correctly, as a patch is needed. I'd recommend upgrading to Sendmail 8.9.1, and applying the following: ftp://ftp.lsoft.com/LISTSERV/UNIX/CONTRIB/sendmail-probe.8.9.1.patch If you need any help/hints on how to do it, check this URL: http://black-ice.cc.vt.edu/~valdis/sendmail.html - I've put pretty much all of our tricks and tuning tips on there. if you still have problems after that, let me know. /Valdis P.S. Ben and the other LSoft guys - the 8.9.1 patch I sent you should work on 8.9.2 when it comes out...
