The site-wide public folder database for administrative group ‘first administrative group’ has been deleted after migrating to Exchange 2007 from Exchange 2000 or 2003

After migrating a SBS 2003 server to a SBS 2008, a good practice is to run not only the SBS 2008 BPA but also the Exchange 2007 BPA built into the Exchange Management Console. In this case, the SBS BPA revealed no issues, but Exchange did. In the Exchange BPA, it was showing

I often have to configure SBS 2008 (Exchange 2007) to allow mail to relay from devices like APC UPS’s, network switches, copiers and other devices or programs on the local SBS SMTP server.
