    WTF is laposte.net blocked ?

    There is a common misconception that blocking spam during the SMTP session is incompatible with giving end-users control over filtering policy. There is also: C. Provide fine-grained end-user control over what rules are used to reject spam at SMTP. see http://www.postfix.org/SMTPD_ACCESS_README.html#relay and http://www.postfix.org/RESTRICTION_CLASS_README.html for how you can do this in one commonly used MTA.
  2. if your list is contaminated with unconfirmed subscribers who happen to be spamcop users or spamtraps, the only way to avoid future spamcop reports will be to start over with an empty list.

    Option to reject HTML mail?

    Filters which run in real time during the SMTP session can return an error to the DATA command based on the message content and have been used to reject HTML-only email.

    Company Outgoing Mail blocked

    .. because that address is a neighber of the incomparable Scott Richter. good neighbor you've got there..

    I find this very difficult to believe -- refusing delivery in SMTP with a 5xx error code I could believe might be far more effective, and it doesn't run the risk of backscatter nailing the innocent.

    My email is blocked

    "System has sent mail to SpamCop spam traps in the past week (spam traps are secret, no reports or evidence are provided by SpamCop).." DId you click through and read http://www.spamcop.net/w3m?action=blcheck&ip= ? appears to be at the far end of a DSL line in poland. Your system may have been compromised and could be acting as a spam relay, or it may be misconfigured to bounce undeliverable mail rather than refusing it.

    Getting blocked even if not sending email

    y'know, when you spew obvious B&^%S$[at]# like that you sound like a spammer. Before you reply, you should be aware that we've all heard these other excuses, too..

    Not receiving any reports

    If you can't figure out how to opt yourself into one of their lists without help from their salemen, it's probably not legit. If you can figure it out, do due diligence: set up a new email address with no obvious connection to your existing net identities. opt it in to the lists you want to "purchase". monitor it for a month or two at minimum and see what you get. My prediction: if you're dealing with a business with "opt" in its name, the new address will become very useful as a spamtrap.

    Not receiving any reports

    Oh, that's an easy question to answer. Why didn't you say that in the first place? For all practical purposes, assume any "opt-ins" list you can buy will be dirty (containing spamtraps and/or addresses who haven't actually consented to recieve mail *from you*) and will result in spamcop reports and other stains on your reputation. By buying them and then sending mail to them, you're engaging in "black-hat" spammer behavior and, in the opinion of many people who care about the internet email system, are not entitled to anything other than disconnection from the internet.

    Note that it appears to be routine for clients to use creative/fraudulent definitions for "opt-in". If you can't figure out how to opt-in, and then opt-out, an address to a client-run list they're probably not really opt-in.

    Infinity Resources?

    That looks like a locally hacked copy of spamassassin; the total score adds up to 5.1 points vs the normal blocking threshhold of 5.0. Of the tags which hit, a bunch of these suggest that the sender's mailer is misconfigured/not standards-conformant. this is usually a good but hardly perfect indicator of spam.

    Getting blocked even if not sending email

    Since when? since shortly after spammers started abusing weaknesses in the mail protocols to obscure the origin of their offal. It's much easier to track down and hurt the spammer via the spamvertised website than via the mail origin. Yes, this is not perfect (see "Joe Job"). But a joe-job victim can often adjust their website in a way that makes it clear that they don't want to benefit from the spamrun.

    What should I do with this?

    So, if they're doing address harvesting from web sites, they're violating CAN-spam -- criminal activity under US federal law.

    Not necessarily. While "can-spam" makes certain conduct illegal, messages which are conformant with the requirements of "can-spam" may still violate *other* laws, Moreover, spammers have been known to lie about many other things -- why wouldn't they lie about whether their excrement is can-spam-compliant?
