It's been doing really well, however I noticed on the report I received on Saturday, it allowed 96% of the email through, whereas before it was only allowing about 28%. I noticed that you and others are recommending placing my local domains in the blacklist-senders file, however, I don't think I'm using SMTP-Auth everywhere so I'm concerned that I'll block some of my users. What would I have to do to enable SMTP-Auth everywhere? Must everyone use the submission port of 587?
