About the "sendmail ... dangerous permission" message: 
I don't know about "Mail -v" but I got that same message from the
system during reboot after I modified sendmail.cf using m4. That process
had produced different permissions from the original, as I discovered
because I had kept the original (by renaming it). Setting the permissions
to the original value made the message go away for subsequent reboots.
