Mail.app and Courier IMAP: The message could not be saved

Mac OS X Mail.app doesn’t properly work out of the box when connecting to a Courier IMAP (Plesk) mail server. If Mailbox Behaviors is configured to save Drafts, Sent, Junk, or Trash on the server then Mail.app will constantly report the error The message could not be saved. Quite annoying and, in the case of […]

Best tech support evar!

One of my co-workers was having problems connecting to the VPN at work and fired me an e-mail: Looks like my IP address at home changed. Would that irritate the SonicWall? My new IP is XXX.XXX.XXX.XXX, can you feed that to the SonicWall? I’ll sacrifice a chicken or two over here, maybe together we can […]

Shespamigans

When training the Bayesian filters for SpamAssassin, be very careful about using sa-learn on your active IMAP inbox. Most IMAP clients don’t actually delete messages until they synchronize the mbox.

2STF/1/4: MAC-IO ata-4 – Master

My rig started freezing intermittently on the evening of the 7th and the two 120 GB drives on my ATA/66 […]

Olympus SmartMedia Card Error: Repairing/Recovering Corrupted Cards

Quite a few months ago my Father gave me a pile of large SmartMedia cards that stopped working in his Olympus digital camera. After a few months of use, each card slowly started reporting CARD ERROR on the camera LCD. I was able to use the cards in various other devices, but they never worked […]

useradd: invalid user name ‘first.last’

Starting somewhere around the migration from Red Hat Linux 9 to Fedora Core, useradd (adduser) stopped allowing dots in usernames. This was all well and good to fix some of the problems that dots can cause under certain circumstances, but it left some systems administrators high and dry when it came to creating new users […]

Best privacy policy ever!

Just in case you were wondering: The Central Intelligence Agency is committed to protecting your privacy and will collect no personal information about you unless you choose to provide that information to us.

We trust you, really! And who were you again?

In theory, the Merchant ID and Terminal ID numbers used to configure a payment processing system and link it to a merchant account are highly sensitive pieces of data that should never be revealed to anyone. With those two numbers, any fraudster could configure their credit card terminal to siphon funds from the account in […]

Linux Process Accounting

When installing a fresh copy of Fedora, make sure to select the psacct and sysstat packages and run chkconfig psacct on to enable process accounting. Always a good thing to have snapshots of activity to show which processes and users are sucking up the most system time and bandwidth. Process accounting was invaluable over the […]
