Using the free Kerio Workspace Starter Edition at Home by Anthony Lawrence
Kerio,Workspace ; 2012/10/14


I immediately saw the value of Kerio Workspace for my business. I jumped right in and added customer information, support renewal dates and used File Library components for scripts I have written for specific customers.

Troubleshooting Kerio Control installation by Anthony Lawrence
Control,Kerio,Security,Troubleshooting ; 2012/10/13


If you have set up any firewall, even if it was only a simple home appliance, you are unlikely to experience any difficulties with the initial setup of Kerio Control. Of course you need to know your basic network configuration, but the setup wizard will ask you for that and do the necessary work.

Training your users to properly train Bayes by Anthony Lawrence
Connect,Kerio,Mail,Malware ; 2012/10/12


Bayesian filtering is part of Kerio's email spam control. While it is important to understand that it is just one part, it's also important to understand the strengths and weaknesses inherent in this type of filtering.

Analyzing some affiliate marketing email spam for Bayesian poisoning by Anthony Lawrence
Kerio,Mail,Malware ; 2012/10/11


A large percentage of the spam email we get is from affiliate marketing. That is, someone who wants to sell something offers a commission to people who send them buyers. People hoping to make money post affiliate links at their websites (I do that here for a number of products, but mostly for tech related books I have reviewed or mentioned) and others send out blind mailings to you, me and everyone else whose email address can be found, bought or stolen.

Basics,Linux,MacOSX,Perl,Scripting,Shell ; 2012/10/09


I learned the rudiments of shell scripting at the keyboard of a Tandy TRS-16 computer in 1982. A few years later I found The Unix Programming Environment and upgraded my knowledge significantly.

Upgrading to Ubuntu 12.04 LTS Server by Anthony Lawrence
Install-Upgrade,Linux ; 2012/10/08


I host this webserver on a Linode server. When I first set it up, the latest available Ubuntu choice was 10.04 LTS, so that's what I picked and it has been running great ever since. I've had a very few outages (one from a construction crew cutting a major data pipe, one from a severe power outage at the hosting center and one from hardware failure) but they have been brief and the Linode team was very good about keeping me informed of progress.

No clobber scp - scp without overwriting by Anthony Lawrence
Basics,Linux,MacOSX,Scripting,Shell ; 2012/10/07


I don't allow ftp to my website. The only access I allow is ssh, which means I need to scp files and images that I want to add there.

Using Kerio's Linux Versions by Anthony Lawrence
Kerio,Linux ; 2012/10/05


I really can't tell you how many times I have recommended a Linux version of a Kerio product and have heard "But I don't know anything about Linux!". I do understand that fear and hesitation, but it's really not justified. Let me explain why.

Greylisting in Kerio Connect by Anthony Lawrence
Connect,Kerio,Mail ; 2012/10/03


Kerio Connect will be adding greylisting in the 8.0 release (most likely coming late 2012). Beta versions of this have been available for some time now, and have caused a good deal of confusion and misunderstanding in the Kerio beta forums.

Deleting Kerio Connect Users by Anthony Lawrence
Connect,Kerio,Mail ; 2012/10/02


I'm sorry, Ralph, but I have to remove you from my mailserver again. I know, I've done that before and reinstated you again and again and I suppose that you have reason to feel singled out and mistreated. But you ARE just a test account, Ralph, so you have to expect a few indignities.

Transferring Linux or Mac Perl scripts to Windows Cygwin by Anthony Lawrence
Kerio,Microsoft,Perl,Scripting ; 2012/10/01


I've put up quite a few Perl scripts here over the years. A number of them are for accomplishing various tasks related to Kerio products. While I certainly strongly recommend that customers choose Linux or Mac over Windows, not everyone takes my advice, which means that the Kerio related Perl scripts aren't necessarily immediately useful to everyone.

Kerio Operator in a separate subnet behind Control Firewall by Anthony Lawrence
Control,Kerio,Operator,Security,VOIP ; 2012/09/29


A customer recently installed a Kerio Operator appliance behind a Kerio Control Firewall. Although his LAN is presently small enough that he could have put Operator and the phones on the same subnet as his computer network, he expects to grow, so Operator was put on a separate internal network. This avoids some traffic congestion (the firewall is still a choke point, however) and adds some additional security.

Examine Kerio Connect User Spam Activity by Anthony Lawrence
Connect,Kerio,Mail,Malware ; 2012/09/29


Users will always complain about spam. No matter what you do, either some message they don't like will end up in their inbox or something they did want will get put in their spam folder. You can't avoid that, but knowing more about what the users actually do can help you fine tune your spam settings so that you (hopefully) get less complaints.

Kerio Connect Failover and disaster planning by Anthony Lawrence
Connect,Kerio,Mail ; 2012/09/24


I'm often asked what can be done to be sure that email remains available in the case of major hardware failure or Internet outage. My usual answer is that you probably don't need to do anything.
