Frank,
Great news, I've spoken with Kirk Smith at Postini and it's all sorted
now.
This is a salutary lesson for all the Google Apps/Postini system
administrators out there... never change the domain extension of the
"Primary Address" of your administrative users. I changed this to be a
different domain, a domain which is still within our Google Apps
system (as an alias), however, having done that I could not log in.
Kirk was very surprised that I was able to change the administrative
user's primary email address but it's actually quite simple. From
within the users list you simply select the administrative user and
then the "Primary Address" is available for change under the "General
Settings" section for the user. I guess for Google Apps users changing
this should be blocked (but it isn't).
The problem doesn't appear until you log out and try to log back in
again. The Google Apps dashboard passes only the primary domain
extension (plus the user name) to the Postini log in servers. When the
servers don't recognise the user name in combination with the primary
domain they reject the login. However if you try to bypass the
dashboard and log in to the Postini servers directly, using the
username with the "non-primary" domain, something catches the log in
attempt redirects you to the Google servers where they report back
that the domain extension is not a valid Google Apps primary domain.
This should probably be documented somewhere but until it is I hope
people find this post here.
Cheers,
Sam
