Not sure if you're aware, but the way you mailing list gets sent out it perpetually gets sorted to Junkmail on my hotmail e-mail addresses, even if its marked as a safe sender. I'm assuming others on here are running into this as well, different e-mail clients might treat it differently?
I believe it's due to the way it's being sent out:
Canada Ammo (ryanj=canadaammo.com@mail198.atl171.mcdlv.net) on behalf of Canada Ammo (ryanj@canadaammo.com)
The "@mail198.atl171.mcdlv.net" chunk has different numbers on every e-mail (so I believe it's essentially being recognised as a different address every time)
