Hi Brent Yes the system we are calling X, is jailed by another system.=20 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?

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. > What is non $mail_owner privileges or how to determine that? > > tools2# postconf -d | grep mail_version mail_version =3D 2.7.0=20 > milter_macro_v =3D $mail_name $mail_version > > I am still not sure about the non mail owner issue yet, but I would=20 > think because this has run in the past that it wouldn't have changed. > And how do I run smtp as a non mail user when I am root? > > Hopfully we are getting somewhere.....
