Application Development Software

Hello,
I am trying to release disk space running: imexpire utility.

I have configured store.expire like documentation indicates, but in logs always appear:
[22/May/2005:17:41:49 -0500] delta imexpire[296]: Store Notice: user/usuario/INBOX: expired 0 messages
[22/May/2005:17:41:49 -0500] delta imexpire[296]:
Store Notice: user/usuario/Sent: expired 0 messages
[22/May/2005:17:41:49 -0500] delta imexpire[296]: Store Notice: user/usuario/Trash: expired 0 messages
[22/May/2005:17:41:49 -0500] delta imexpire[296]: Store Notice: user/usuario/Drafts: expired 0 messages

The store.expirerule appears like:
Rule1.regexp: 1
Rule1.folderpattern: user/.*/Trash
Rule1.Subject: .*
Rule1.messagedays: 1

I have modified it trying to make it work but it appears not to do anything.
I have tried the graphic interface with same results.

I'm running:
Sun Java(tm) System Messaging Server 6.2 (built Dec 2 2004)
libimta.so 6.2 (built 00:22:18, Dec 2 2004)
SunOS delta 5.10 Generic i86pc i386 i86pc

Is there any special consideration about this to make it work?

Thanks in advance.
