Sand box errors?  This is what /var/log/system.log records:

Dec 30 18:06:46 MacBookPro postfix/sendmail[35440]: fatal: execvp /usr/sbin/postdrop: Operation not permitted
Dec 30 18:06:47 MacBookPro postfix/sendmail[35439]: warning: command "/usr/sbin/postdrop -r" exited with status 1
Dec 30 18:06:47 MacBookPro postfix/sendmail[35439]: fatal: _lp(26): unable to execute /usr/sbin/postdrop -r: Unknown error: 0

Where do I look next?
