Thanks again to Christopher and Antonio for the help...
The good news is that chkuser is working as expected now. The bad news is that I didn't change anything to make it so. Presumably, my initial test must have been flawed, because it appears chkuser has been running fine for the past 10+ hours. Also, I found the logs, as Antonio pointed out -- qmail-smtpd was logging to /var/log/qmail/smtpd/current (as specified by /var/qmail/supervise/qmail-smtpd/log/run ), and that file indeed contained full chkuser output. Unfortunately the default multilog config (99k, 10 files) saves only about 30 minutes' worth of qmail-smtpd logs, so I can't figure out when chkuser came to life, but it must have been last night because I haven't restarted qmail today. Sorry for taking everyone's time on a non-problem... I don't believe I changed anything since the failed test, but I can't complain about the ultimate result. -- matt. !DSPAM:474aeb5b32001730717885!
