1) Tools -> Mail filtering rules -> Edit new mail filtering rules -> Rules applied when folder is closed
2) Click "Add rule" and choose to create a filter of the type "Attributes"
3) Check the checkbox in front of "Is marked as having been read"
4) Choose the action (copy/move etc) that you want to perform.
If you wish to combine this rule with some matching on other properties of the message such as from/to address, I suggest you take a look at dividing your filters into sections using the "call label" and "return from call" rules.
