[Evolution] Deleting infected messages

[Jonathan Ryshpan <jonrysh pacbell net>]

I've just run clamav on my system and have discovered a number of messages infected by viruses, which I would like to delete.  If this is done, can the index files be recreated by simply deleting all the files of these forms:
>     .foo.cmeta
>     .foo.ibex.index
>     .foo.ibex.index.data
restarting evolution and waiting a while?  

This was true in earlier versions; but I'm not sure now.

Thanks - jon
