Danny,

All those files are leftovers (probably from MS restarts).  They have 
been processed but were partially left behind because of the restarts.  
You can see they are not complete emails because you don't have q* and 
d* files for the same email.

I've ran your listing through "cat -|awk '{print 
substr($NF,2)}'|sort|uniq -c" and all filenames were unique (count=1).

I use the following command when I want to clean up those files:
cd /var/spool/mqueue.in; rm -f $(ls -l|grep -v "$(date '+%b %e')"|awk 
'$1 ~ /^-/{print $NF}')

It removes all files that don't have the current date.

Denis
