I guess it doesn't > really matter that much. If /var/spool/mail is writeable, you really want to set the sticky bit, and make sure that no spool mail folders ever get removed. I'd suggest you rather go with your system's default configuration, which is most likely mode 775, with /var/spool/mail having the group ownership set to mail. In this case, you can fix the problem by adjusting the mutt_dotlock binary's mode on your system (most likely, that's /usr/local/bin/mutt_dotlock): chgrp mail /usr/local/bin/mutt_dotlock chmod g+s /usr/local/bin/mutt_dotlock Hope this helps. -- http://www.guug.de/~roessler/
