TrendMicro blocking Gmail
It looks like Trend Micro is now completely blocking mail from Gmail accounts:
Technical details of permanent failure:
TEMP_FAILURE: Gmail tried to deliver your message, but it was rejected by the recipient domain. The error that the other server returned was: 450 450 5.7.1 Mail from 64.233.166.177 blocked using Trend Micro Network Reputation Service. Please see http://www.mail-abuse.com/cgi-bin/lookup?ip_address=64.233.166.177.
I think that Herby's idea has some merit. Forcing users fill out a captcha for every email is too inconvenient, but getting users to fill out a captcha IF their email looks like spam, is less so. That is unless you happen to be a legitimate Viagra salesman. Things are really hard for them these days.
It would be too expensive for spammers to pay for a captcha to be solved by humans for *every email*, even using third world labour.
Paris, because she could make things hard for a Viagra salesman
