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 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.

Hello CSC,
Computer Science Club systems and services will be unavailable on
Saturday, Mar. 20 due to a planned power outage in the Mathematics and Computer
Building (MC) from 7am to 5pm.
The CSC will begin shutting down machines at 6am in preparation of the outage.
This outage will impact:
- Web hosting (all personal and club websites)
- Email (@csclub.uwaterloo.ca email addresses)
- General-use machines
- The Lounge
- ZNC
- BigBlueButton
- Mattermost
We are hoping to keep mirror.csclub.uwaterloo.ca available for the
duration of the outage using a backup mirror.
Please prepare for the outage by:
- Ensuring all running processes have their state saved (configuration, data,
etc.)
- Any important files are backed up off-site from the CSC
If you have any questions/concerns, please email the Systems Committee at
syscom at csclub.uwaterloo.ca
