The departmental servers coxeter, sphere, and the mail, web, and blog/wiki servers will have software updates applied tomorrow (Wednesday afternoon, June 29, 2011) which will require rebooting (most servers will be unavailable starting at 4:15pm). Since some updates will be applied while the servers are still up there may be some temporary issues with some software. We hope that any such issues will be minor and by doing most of the upgrading before bringing systems down the shorter downtime will be worth the potential minor problems. Please restart any programs if you observe problems during the upgrades (and please let us know at requests@math.toronto.edu, so we can investigate). We expect the systems to be back up by 5:00pm.

It is recommended people refrain from editing pages on the blog servers during these updates to avoid losing work.

Server upgrades taking somewhat longer
Due to a download problem with the remote server and some file-checking the update of coxeter is taking longer than anticipated. We expect things to be back up by 5:15pm.
Server updates on 2011apr06 were NOT carried out
The remote update server was not available, so today’s updates will have to be postponed until tomorrow (Thursday April 7) at 4:15pm. Sorry for the inconvenience.
Controlling spam in your email
There is a new command on coxeter called spamfiltering_gui which is a simple graphical interface to change email spamfiltering options (there is a command line interface called spamfiltering). You can change three options via this new interface:
Aggressiveness from 0 (off) to 9 (extremely aggressive). This controls how many messages will be put automatically in your SuspectedSpam folder, instead of being delivered to your main mailbox. This is based on an estimate of the likelihood that a message is spam.
Autoexpire can be off or on, and if it is on you can choose how many days to leave messages in the SuspectedSpam folder before they are deleted by the system.
Autodelete can be off or on. This automatically deletes messages which are judged as being spam with probability 99% or 100%. It is highly recommended that this be left on, which is the system default.
