That would only be 42 email addresses, so not *too* painful, but if their email requires a 'challenge-response' to send to them, how did they get subscribed in the first place, as our subscribe method is 'challenge-response' also, which means they have to receive the email we send to them automaticalloy in the first place ... So, are these a result of forwarding, vs direct subscription?

That's kind of what I'm wondering, which makes it even harder to track down ... But, as I've said, if someone wants to write a good, well worded email, I have no problem with doing a quick for loop to send out one message per user, maybe with a counter in the subject line, and see what bounces back for those .br addresses *shrug* - -- Marc G.

'k, just checked and yes, we have blocked one Brazil domain in the past because of this issue: subscribe deny, reason="uol.com.br requires non-spam confirmation ..

If someone wants to write up a nice form letter, I can send out an individual message to each user in the *.br domain, and for each that bounce back with a 'confirmation required', remove them ... but I'm not sure if it makes much sense to go through the confirm and see if they can work around the issue ... ---- Marc G.

Note that you need to put the individual subscriber in the To header. The worst problem with this amazingly brain-dead spam filter is that it doesn't give you back any other info about the original email aside from the From header and the To header. -- Gregory Stark EnterpriseDB http://www.enterprisedb.com Ask me about EnterpriseDB's RemoteDBA services!
