Sometimes we have emails going to a particular address, which cannot be stopped. There are many reasons, but most common is an invalid address, which pollutes the mail queue with invalid entries. The simplest way to solve this is by adding a DISCARD directive for postfix.
If you don't have it already, add this line in main.cf
header_checks = regexp:/etc/postfix/header_checks
One of our IT Support clients asked us why some emails are coming in with extra HTML content. After some searching, we've discovered that is was due to the MailScanner antispam system: it was parsing emails improperly and adding extra junk. We have decided to solve this by skipping the email from that domain from being scanned altogether.
One way to do so is to change the Scan Messages directive in MailScanner.conf from:
Scan Messages = yes
Scan Messages = %rules-dir%/scan.messages.rules
Then, in your rules directory, create a file called scan.messages.rules. In that file, be sure to add the line for scanning all by default:

The suspension of sales comes after a growing suspicion about the company's relationship with the Russian intelligence service, which is not a big surprise: a report from Bloomberg in 2012 had discussed founder Eugene Kaspersky’s ties to the Russian FSB and his background in the state-sponsored cryptography research. It also mentions that the firm has let go of a number of high-level employees in 2012, replacing them with individuals with close ties to Russian intelligence.
There are many instances when programs are starting when the computer boots, bring annoying pop-ups and consuming resources. Most of them have a way to disable that feature, some of the more poorly designed ones do not. There's a way to disable it, using an configuration application called msconfig. It exists in all modern Windows versions:
Go to Startup Tab and uncheck any application you don’t want to launch during boot time. Click Apply and then OK.
We'll use Ubuntu for this example, but essentially you need an ntfs-3g package, which contains ntfsfix. Under Ubuntu, run the following to install it:
sudo apt-get install ntfs-3g
Then this (where /dev/sdd1 would be your ntfs disk):
Depending on what you are trying to fix, you may want to use options -b and -d.
