Hello CSC,
Some time this week, we will be making changes to our SpamAssassin configs
to use a site-wide Bayesian learner instead of per-user. Given that the vast
majority of our spam is directed towards our mailing lists rather than
individual club members, I think this makes the most sense for us. We
will also be increasing the scores for the Bayes tests to keep spam out of
our inboxes more aggressively.
Unfortunately, this means that there will likely be some false
positives. I will try to …
[View More]adjust the Bayes test scores to keep this rate
low. Alternatively, you can set your own custom scores in
~/.spamassassin/user_prefs.
This means that all of the bayes* files in everyone's ~/.spamassassin
directories are now useless. If these files are taking up a lot of
space, it would probably be a good idea to delete them.
As a final reminder, SpamAssassin only adds headers to emails which it
flags as spam - it does not actually delete or move them. If you wish to
invoke some custom action on these flagged messages, you can use a
custom procmailrc file, as outlined in our wiki:
https://wiki.csclub.uwaterloo.ca/Mail#Spamfiltering
If you have any concerns or suggestions, please send a message to
syscom(a)csclub.uwaterloo.ca.
