Help needed please.

We have just upgraded our Gwia from version 8 to the hotpatch version.

The Gwia is running on Bordermanager 3.9 sp2, and after the upgrade we are seeing 450 errors are no emails are going out or coming in.

Named is running, DNS is fine, we have a resolv.cfg set correctly and a route'cfg setup correctly.

You can resolve address if you ping them from the server. Does anyone know if there have been changes to the TCPstack or anything such as that.

We are pulling our hair out here. I miss my hair.

By the way the server is behind a pix firewall.

Thanks in advance
