Yep, I know about that, but if I want mail delivered, I wouldn't rely on
it. If there's a network outage, or the destination server is not
accessible for whatever reason, busybox's sendmail will not attempt to
re-deliver the message.

My driver will notice such outages, and keep the message in its queue,
thus, preventing message loss. This also guards
against /usr/bin/sendmail failing for whatever reasons
(misconfiguration, upgrade in progress, break-in, and so on).

Nullmailer or similar small solutions can help with that, of course, but
why would I want to install nullmailer, when syslog-ng can do the
mailing without external help?
