Apple Event: May 7th at 7 am PT
This is on a clean, default Lion Server install:
# postfix check
postfix/postfix-script: warning: not owned by _postfix: /Library/Server/Mail/Data/mta/./greylist.db
postfix/postfix-script: warning: not owned by _postfix: /Library/Server/Mail/Data/mta/./whitelist.db
postfix/postfix-script: warning: group or other writable: /Library/Server/Mail/Data/mta
Are these warnings of concern, and if not, is there a good way to suppress them?

The message "not owned by" means that the file has a wrong owner. You can check it by
$ sudo ls -l /Library/Server/Mail/Data/mta/./greylist.db
To fix it you can change the owner with chown:
$ sudo chown _postfix /Library/Server/Mail/Data/mta/./greylist.db
The message "group or other writable" means that another user (not the owner) is able to write. You can fix it with chmod. Example to remove group write permissions
$ sudo chmod g-w /Library/Server/Mail/Data/mta
While those commands will get rid of postfix's complaints, they will also break the graylisting. You'll start seeing things like:
/usr/libexec/postfix/greylist.pl[39949]: fatal: Cannot open database /Library/Server/Mail/Data/mta/greylist.db: Permission denied
postfix/spawn[39948]: warning: command /usr/bin/perl exit status 1postfix warnings
