I wrote DH support regarding entering negative quarantine numbers and spam reporting. The response was to blacklist more. Unfortunately that doesn’t work. Blacklisting is a bad way to deal with spam. I’ve blacklisted over 40 domains since the spam increase and that hasn’t stopped the spam as the spammer can just keep using new domain names. If I could use a negative quarantine number to block all email and only whitelist the stuff I want that might help.
I checked into reporting spam to Spamhaus (the filterers used by DH). They don’t accept outside spam reports. They say they have a team of people around the world checking for spam but, unfortunately, they aren’t getting the spam I’m getting. I wish DH and/or Spamhaus had a way to report spam.
Using Spamhaus is a step in the right direction but it doesn’t always work. There must be something else DH could do to help. I’d rather not install SpamAssassin etc. myself as then that is just something else I have to maintain. I’d rather my email just work.
I’ve also set up some filters to filter out commonly used terms in the spam headers. Unfortunately that’s just a time consuming stop gap measure to help cut down some of the most frequent spam. See http://wiki.dreamhost.com/Message_Filters for info on filtering.
To be fair, DH has caught 107 spam messages in the quarantine since 2014-04-08 10:54. The scores range from 0.002 to 13.503 (I have the quarantine level set to .0). 16 messages have scores less than 2. 15 of those values are less than 1. 32 messages have a score higher than 2 and less than 3.
If I had the quarantine set to 3 I would have let an additional 48 spam emails through.
As mentioned earlier, other spam messages getting through have had a score of -0.009.
What are others seeing for spam scores?
