[CentOS] rsync question

I run several backup scripts by cron, one of which backs up my mail.  I do not 
want it to back up the Trash folder, but it appears to be doing so.  I 
conclude that my script is faulty somewhere, and would be grateful for 
advice.

The command is

rsync -auvz --delete-after --exclude-from=/home/anne/rsync_skiplist_mail.txt /home/anne/Maildir/ /Data3/anne/Maildir/

where rsync_skiplist_mail.txt says

*~
.[a-z]*
.[A-Z]*
Maildir/.INBOX.Bugs/
Maildir/.Trash/

Comments, please?
