Hello all:
Per my usual style, I have a few questions.

First, I set up Postfix on my host system and that's what all email 
should be running through. I'm noticing though that some jails are 
running sendmail processes--possibly to try to get out some kind of 
emails (periodic, I'm guessing).
Is there a way to remove sendmail altogether and force all jails or all 
services to send mail to the host IP? I can enable relay for those if 
that's what's needed, but I'd really like to filter everything through 
postfix sendmail.

Finally, I'm noticing that some of my jails are falling behind in terms 
of updates. I use ezjail; I upgraded to pkgNG on the host system and 
other jails are still running behind. This makes sense, but I'm curious 
what people use to help keep jails updated. Most importantly, I'd like 
to be able to update ports and run freebsd-update (is this needed) from 
the jail on cron. the freebsd-update works, but it returns errors about 
a kernel (which is pretty much to be expected).
Thanks in advance for any info--I really appreciate it. Appologies as 
well for all the questions; I'm making my way from Linux to BSD and 
trying to be a useful server admin. With my luck I've probably already 
got a few people doing evil things with it, but I'll learn in time.

Take care,
Ty
