I was surprised at first to see that a long-standing bug in dspam had been fixed. Until that is, I realised it was from the Debian ftp masters and the reason the bug was closing was that dspam was being removed from the Debian archive.
So, now what? What is a good replacement for dspam that is actually maintained? I don’t need anti-virus because mutt just ignores those sorts of things and besides youbankdetails.zip.exe doesn’t run too well on Debian. dspam basically used tokens to find common patterns of spam and ham, with you bouncing misses so it learnt from its mistakes. Already got postgrey running for greylisting so its really something that does the bayesan filtering.
Some intial comments:
- bogfilter looks interesting and seems the closest thing so far
- cluebringer aka policyd seems like a policy and bld type of spam filter, not bayesan
- I’ve heard crm114 is good but hard to use
- spamassasin – I used to use this, not sure why I stopped
There really is only me on the mailserver with a pretty light load so no need to worry about efficiencies. Not sure if it matters but my MTA is postfix and I already use procmail for delivery.
