Hard white listing with amavis-new

Previously I had discussed white listing in Amavis, which is a soft white list.
When this continues to fail it is time to modify the Perl code of “20-debian_defaults” to include a hard white list.

Choose a blank space in the Perl code before the soft white listing section, and create a new ARRAY.
Call the array @whitelist_sender_maps and include the domains that you want to globally hard white list.

Here is an example:

@whitelist_sender_maps = ([‘.somedomain.com’.’bronson@bronsonitinnovations.blogspot.com’])

Note: there is a “.” Before globally hard white listing an entire domain.

Data Migration with Symantec CPS

Don't do it. This is just a bad idea all around. I recommend using WanSync if you are afraid of XCopy.

Checking free disk space on Debian systems

A great APT package to use for checking free disk space is "discus". Discus displays disk usage of each file system in a textual bar graph format.
Install with
apt-get install discus
Output appears as such
