Did you customize an existing Debian package or install from the upstream

This is bad. I would recommend that you either modify the package from
Sid to your liking and use that (essentially backport it yourself) or
remove the postfix* package(s) you have installed (you can force the removal
process to ignore dependency checks) and then install a dummy package
created with equivs. equivs is very easy to use and allows you to create
"fake" packages that make dpkg think that you have installed a particular
package with a particular version that provides whatever you it to provide
and depends on whatever you want it to depend on.

Set the pakcage status to "hold" through your package management program.
