Greetings, Has anyone run into this problem before?
It turns out that in all versions of RedHat Linux between at least 6.2 and 7.3, /bin/ps will refuse to run when called by a "c" executable (like vqadmin.cgi) running SUID root. The result is that when you add a new domain, a HUP isn't sent to qmail-send, so it doesn't register the new virtual domain entry in rcpthosts and virtualdomains and bounces mail for any newly added (by vqadmin) domain until you HUP qmail-send manually... --Duncan
