>Description:
cron(8) tries to send mail without specifying recipient.
It really seems to be bug in nsswitch mechanism because of these log
entries (from /var/log/cron):
Oct 10 21:30:00 capella cron[13567]: NSSWITCH(nss_method_lookup): nis, group_compat, setgrent, not found
Oct 10 21:30:00 capella cron[13567]: NSSWITCH(nss_method_lookup): nis, group_compat, endgrent, not found
Oct 10 21:30:00 capella cron[13567]: NSSWITCH(nss_method_lookup): nis, passwd_compat, endpwent, not found

I have 'NO_NIS=yes' in /etc/make.conf and default /etc/nsswitch.conf.

>How-To-Repeat:
Build a system without NIS, then try to cron a non-silent program.
Observe no mail (or negative delivery notofication).
