I accidentally managed to "chown virtualservername /etc -R" and then used "for p in $(rpm -qa); do rpm --setugids $p; done" which seemed to restore ownership to just about everything. However now no mail is delivered to any mailbox on the server. /var/log/procmail.log is always empty.
After sending a test piece of mail to a mailbox, maillog shows:

Jul 24 07:56:10 f postfix/qmgr: 2DABBC007CE: removed
After this, the email is never seen again. Does anyone have any suggestions? Thanks.
