I downloaded the FBSD build of psa7 tonight and installed it on my personal/beta box, upgrading from psa6.02. So far the only issue that has crept up is this. During the upgrade process the files /usr/local/psa/qmail/users/poppasswd and assign were pretty much garbage.... Almost all the email accounts were dysfunctional right after the upgrade. I had to copy my backup poppasswd and assign over the new ones aftewards mail and things seem to start working in that area.
