Apple Mail RSS folder is Huge > How to clean up?

[SACD02]

I checked my mail folder in library and the RSS subfolder is 4.32GB. It seems to me that Mail doesnt delete the previous RSS articles (although I have deleted them from inside the mail) hence the massive size of the folder

I tried deleting the folder, but then all the RSS feeds were gone when I launched Mail again. Is there anyway to reduce the size of this folder and delete the old articles without having to delete all the RSS feeds (and the folder itself?

Is there an option to force Mail to compact its files? I'm going out on a limb here, as I don't use Apple Mail.
