The Underscore Archives

Interesting to see your stats Oliver! We've implemented a spam filtering 
system designed to block auto-generated spam, whilst making sure that 
email from existing contacts don't get marked as spam. Rather than 
trying to identify spam with ML techniques, we send a challenge mail to 
any new contact, and ask them to solve a captcha. They only do this once 
to get onto your allowed contacts list. Any outbound mail causes the 
recipient to be pre-authenticated, so if you send someone a mail they 
don't have to authenticate when replying.
