Y2K10 Bug

Since the beginning of the year, I’ve noticed that I had started to catch good email in my Mac OS X Server’s email spam filter. It was odd, since it generally works quite well, and rarely catches any “false positives.” This morning at my office, one of the guys I work with was having to patch one of our systems because of a “Y2K10 bug” where the date isn’t interpreted correctly. Later, I noticed on Slashdot there was a story about the Y2K10 bug affecting a large number of systems around the world.

I did a quick search for Spamassassin, and found that it was suffering from a bug in a date rule! Apple has a technical note on the issue:

Mac OS X Server v10.5 and 10.6 use SpamAssassin to filter “spam” from inbound messages; SpamAssassin includes a rule that increases the spam score for any inbound message sent on or after January 1, 2010.

This increased score may cause some inbound messages sent on or after January 1, 2010 to be inadvertently filtered as spam.

There is an updated spamassassin rule that fixes the problem as well. Run the command:

sudo sa-update –nogpg

to apply the new rule. The –nogpg flag is needed for OS X Server since it doesn’t have GPG installed by default.

Updates and Desktop Pictures

I’ve come to the realization that spammers have used a web crawler to harvest email addresses from my website, so I’ve removed all of the email links, including the pages for Friends and Family. I will clean up those pages and link them back in as soon as I have time.

At a recent MacinTech officers meeting, we had a brief discussion about “Desktop Pictures” (that would be “Wallpaper” if you are PC-inclined). I decided that I would post some of mine as samples. These are some of the pictures that I’ve taken over the past couple of years that I use as desktop backgrounds.
