I had an interesting email discussion today with a guy who runs a mailing list and sends email with an invalid sender ([EMAIL PROTECTED]). I'm using IMGate as a front end and rely on sender address verification as one way to reject spam.
Anyway, I emailed the guy and suggested that he use a valid email address as the sender. He wrote back telling to gray list and use Spam Assassin, or to white list his sender. I thanked him for writing but told him that I would not white list any sender and that, while he was free to send email with an invalid sender, I was free to refuse to accept email from such senders. He wrote back telling me that what I was doing was unheard of. So, I'm writing to the list to ask first how many use sender address verification in their anti-spam process, and whether it is reasonable for a company to send email using sender addresses that they refuse to acknowledge as valid. Personally, I think this is similar to me mailing a letter to someone with "No Valid Name / No Valid Address / Don't Write Back / I Won't Get It" in the upper left as the return address. If I got a letter like that, I'd throw it right in the trash.
