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

Hi Brent
Yes the system we are calling X, is jailed by another system.
Here is the jailer system:
zs1# netstat -aptcp | grep smtp
tcp4 0 0 tools2.smtp 10.156.31.20.45081
SYN_RCVD
tcp4 0 0 tools2.smtp *.* LISTEN
tcp4 0 0 rt3.smtp *.* LISTEN
tcp4 0 0 npims.smtp *.* LISTEN
tcp4 0 0 wiki.smtp *.* LISTEN
tcp4 0 0 localhost.smtp *.* LISTEN
I see smtp running on several systems it has jailed including system X.
I see above a smtp conversation between system X and 10.156.31.20.
But that is never delivered from what I have seen. I am not sure about
the queues
Or how to see in postfix what exactly is happening?
I think a lot of this stopped working after we rebooted the jailer
system. Jails really should have no affect on
This it is a virtual machine essentially, at least that is my thoughts.
What happen to your thought that snmp needs to run as a non mailer
system?
Thanks
regards

Ok. I'm stabbing in the dark here, but didn't you say that X was a jail
system?
Is every postfix process in a jail?
I have never used a jailed system. So my WILD guess it's a something
with jail, or jail setup.
