>Nah, about 2% of my "Thank you for ordering, here is your receipt" mails also get marked as spam. i see about the same thing. and i'm purely sending transactional receipts (that is, immediately after purchase. not for subscription or pre-order or something disconnected from the user having just entered their email in the "send my receipt to" field) and for non-trivial amounts (averaging around $100). i can't understand how so many people mark them as spam, and although i have no evidence to support it i have to assume that some poorly-configured firewalls are sending spam reports automatically.
