sendmail changing messages after MailScanner finishes...

Are the files in /var/spool/mqueue set to rw-rw----? If not, then what?
MailScanner doesn't change the permissions on clean messages, it just moves
If I have to change the permissions as well, that's yet another system call
and another disk write for each message, which I would like to avoid if I can.

Are *all* the files in /var/spool/mqueue 666? Or are ones that were
infected 600?
What are the permissions on all the files in /var/spool/
As you see from below, MailScanner sets its own umask to give 600 files,
specifically to stop problems like this.
