Spamassassin Upgrade
—
by
Yesterday afternoon I upgraded our version of Spamassassin from 3.1.0 to 3.1.1. I also ran sa-update so that it would download any new or updated rules. My hope is that this newer version will do a better job at catching the recent stock pumping spam we have seen lately where it is mostly a bunch…

Unexpected Downtime
—
by
At about 12:35pm today, both of our servers that provide home directory access and email access (woof and meow) decided to call it quits and kernel panic. Both were restarted by 12:55pm. Luckily downtime was not too great, but it is very troubling that they both died when they did. No word yet on what…

Wireless Updates: The big news this week has been wireless. Since the last update we have added wireless to Rundstrom and Norelius. From our stats, it looks like the students in Norelius are really making use of it. (110 devices in the past 24 hours) We also ordered another 60 access points due to arrive…

Email Delays
—
by
Late yesterday afternoon we were hit with a particularly large batch of spam comming from computers spread all across the internet. Then, due to a slight loophole in our mailservers configuration for blocking spam, the spam ended up in a loop taking up more resources that it otherwise would have. The end result was that…

Internet Bandwith Increase
—
by
In an attempt to keep up with the ever increasing demand for more internet bandwith, today we increased our connection from 20Mbits to 30Mbits. Enjoy the extra speed while you can. I’m sure the students will find plenty of uses for it come next week 🙂

At about 8:30pm tonight, our IMAP and POP server died. As a result webmail and any other email client was unable to login and read messages. During this time our mailservers dutifuly stored the mail until just before 9:00pm when the IMAP and POP server was restored.

This Weeks Status Update
—
by
Microsoft WMF Vulnerability: Obviously the big story this week was the Windows WMF vulnerability. I think we caught this one early, told people how to avoid infection, and now with the Windows patch being available, are fairly safe. I am still worried that a lot of computers were silently infected with some spyware, but chances…

This weeks update
—
by
Well, we got a lot of things done this week since it was so quiet. At times we were a little too brave and broke a few things when we should not have, but in the end a lot was accomplished. Reducing duplicate email messages – We put in place a procmail script that checks…

Postifx and Authentication
—
by
After updating one of our 2 postfix mailservers we discovered that some email clients can’t deal with all the authentication options our mailserver presents to them. For example Eudora has an issue if postfix says it can do CRAM-MD5 as in the following example: 250-AUTH PLAIN DIGEST-MD5 LOGIN CRAM-MD5 250-AUTH=PLAIN DIGEST-MD5 LOGIN CRAM-MD5 For some…
