Hi all,

I'm seeing a random issue with my procmail filters (only on email from  
this list) where once every so often, it will fail to filter a  
message. I am sorting by the to/cc email address, and this rule works  
on 99.9% of posts, however every now and again, I see something like  
this happen:

procmail: Notified comsat: "netwiz at 0:/home/netwiz/Maildir/new/ 
1199459595.7065_1.zeus.crc.id.au"

Most posts work perfectly, and show up as such:

procmail: Notified comsat: "netwiz at 0:/home/netwiz/Maildir/.CentOS- 
Discussion/new/msg.gr32"

File and directory permissions on my Maildir directory etc are fine,  
and I'm at a loss to explain this. I've run fsck over the disk with no  
sign of errors.

Has anyone stumbled upon this before?
