backscatter / ndr / smtp auth issues

[Garrod M. Alwood]

You can upgrade to the newest version in ubuntu as well as soon Jules puts the deb packages I sent him. So keep an eye out for that if you like ubuntu.

My mailscanner is running in a gateway setup for multiple domains on ubuntu 8.04LTS / postfix
Mailscanenr version is 4.58.9 (*duck* I know! Im going to migrate everyone to a brand new updated version on centos very shortly.. :-/ )

I have smtp auth enabled in postfix according to documentation found on mailscanner.info<http://mailscanner.info>… so im not sure why my gateway is even sending bounces
