If you're reading this message, it's probably because my servers rejected your email, because your email came to my servers through Commtouch's (aka Prontomail's) address space.
Email servers in Commtouch's address space are not allowed to send mail to my email servers. My servers are my private property and nobody is paying me to use them. So I can run them any way I want. They're my personal servers. A few hundred of my friends use them, too, but that doesn't change anything. It just tells me most commercial ISPs are doing a rotten job if all these people would rather use a friend's service, with no written contract and no guarantee.
Commtouch offers a "free" email served called Prontomail. I don't know why anybody runs "free" commercial email, and I don't care. The only email I ever receiv referring to Prontomail.com addresses is spam. Often the Prontomail.com address is in the message body, so there is no way to filter on it until the message has been received. I figure the spammers must know Prontomail won't terminate them.
If I never received legitimate email from Hotmail and Yahoo users, I'd block Hotmail and Yahoo, too. I'm gonna block Excite any day now.
If your not a spammer and you're having trouble reaching me, try sending from some other server.
Commtouch has called me to make veiled threats of legal action. That was rude, and stupid. They tried to bluff me about some California regulation. (Maybe they were confused. There is a California law that says if you spam you have to put "ADV" in the subject line, but it doesn't require anybody to accept anybody else's mail, with or without the "ADV." If their lawyer told them it does, they need to get a better lawyer.) There is no law that says I have to accept email from anyone.
Maybe I'll stop getting spam with Prontomail reply addresses. That would show that Commtouch has gotten serious about the problem, and the spammers have figured it out. Before they made their threats and called me "immature" for protecting my computers from their customers spam, stopping the spam would have been enough for me to restore their privilege to email me and my friends. But now I know they're willing to try to force their messages onto my equipment. I don't let people like that use my computers, sorry.
If 1% of the 24 million businesses in the United States sent you a spam once a year, your email would be unusable. It would not matter at all if they had "opt-out" provisions.
To prevent the email system as we know it from being destroyed, responsible Internet access providers do not allow spamming. "Opt-out" is irrelevant.
If you had a legitimate reason to send email to a domain I serve, you can
If you find this policy inconvenient, your complaint is with Commtouch, not with me. Contact Commtouch and tell them what you think of their policy of letting their drop box customers send all the spam they want.
If you're a spammer, rot in hell.
