Re: AW: [anti-abuse-wg] how to detect spambots - SPAMTrusted

To add my 2 cents: We enforce limits on outgoing email via our SMTP servers both quantitative and qualitative. Regular users can send only a limited number of messages per minute that do not contain viruses and the spamassassin score is below a certain threshold. Still there is the issue of bulk mail servers for Businesses, but we do not guarantee service there. I.e. we tell our customers that if they manage to blacklist the server then de-listing it is a low priority issue with my team.
