Problem with Debian package's interaction with mail server

[Josef Spillner]

Hello,

One of my scripts installs the oldstable (lenny) package of Noosfero along 
with a debootstrapped basic Debian installation in order to generate a small 
live demo VM. This process has worked flawlessly since its inception about two 
years ago on my machines.

Recently, I've had to work in a changeroot environment to run all of these 
scripts on a foreign system. This system runs a Postfix server which is not 
under my control. It appears that as opposed to the Exim server normally 
present on my systems, it rejects emails immediately and hence lets the 
Noosfero package installation fail when the template user email is about to be 
confirmed.

Is there something which can be done in the short term about this issue, such 
as catching this exception in the Noosfero code, or even some configuration 
hint without modifying the package?

If the stable (squeeze) package doesn't have this issue, I might as well 
upgrade to it, although I'd like to keep the changes to the VM build scripts 
as non-invasive as possible for the time being until the next release.

See below for the installation failure log.
