Email issues, relay failure, perhaps Jails is causing it.

This is my strong suspicion as well.

To separate out what the problem is:

'su' to root in the jailed system.  Shut down postfix.  (`postfix stop`, or 
`/etc/rc.d/postfix stop`)  Then run `nc -l 25`.  This will echo anything 
that comes in on port 25 direct to your terminal.  Then try telneting to 
it.  If it works, the problem is postfix.  If it doesn't, restart postfix 
and ignore it: It's not the problem.
