Sieve issue marking messages "Read"

[Quanah Gibson-Mount]

Hello,

The mail server I use here at Stanford was recently upgraded to include 
timsieved.  It is running without any local modifications.  I'm now doing 
testing of its functionality, and I've noticed that for a few of my 
mailboxes, the messages are marked "read" after being stored into their 
folder.  Is this a known issue?  Is there something I need to do to prevent 
this from happening?

My rules all take the form of:

if anyof (address :contains "To" "directory-team at lists", address :contains 
"CC" "directory-team at lists") {
	fileinto "INBOX.itss.TSS.directory-team";
	discard;
	stop;
}

Where To/CC/From are what I filter on, then file into the appropriate 
folder, discard the message, and stop any further evaluation.
