Archive
I also use the webmail, rather than having them forwarded. I've got, oh, half a dozen or so in my Archive folder there, all much older than 10 days. Any way those could be exempted? If not, give me a heads-up so I can forward them to myself at another address.
BTW, I try to get there once a day to clean the spam out. Mine averages around 50/day; approximately 90% of which are about something I have no problems with whatsoever.
