This smells of the submission smtpd(8) being chrooted in master.cf(5)
and there not being either a usable "etc/hosts" in the chroot jail,
(other potentially missing files include "etc/nsswitch.conf" and
"etc/resolv.conf"). Bottom line, "localhost" fails to resolve to
an address with an "ENOENT" errno.
