Professional firewall for private use

I've already told you a bit about what my private infrastructure looks like. I use a Sophos UTM as my firewall, which has replaced my old Fritzbox. Michel has kindly put the hardware configuration for the UTM online on his blog: http://networkguy.de/?p=269 I have the same hardware except for the SSD. My ... Read more

Exchange 2013: 2 articles about the new architecture

The Exchange Team Blog has published 2 nice articles about the new Exchange architecture: http://blogs.technet.com/b/exchange/archive/2013/01/25/exchange-2013-client-access-server-role.aspx and http://blogs.technet.com/b/exchange/archive/2013/01/23/exchange-2013-server-role-architecture.aspx Both articles are well worth reading in my opinion. Currently the SP3 for Exchange 2010 is eagerly awaited so that the migrations can finally start. Unfortunately, there is still no news on when the service pack will be released. The date ...

Exchange 2010: Edit junk mail filter rules with the Exchange Management Shell

Exchange 2010: Set up IMAP access and test via Telnet (special case)

Today I came across a rather interesting archiving software. The software archives mails from the Exchange Server, is also compatible according to the manufacturer, but cannot handle a journal mailbox.

Powershell: List overlong file paths

This small Powershell script can be used to identify such long paths: #Directory or volume to be checked: $Directory = "D:\Shares" #PPath to CSV file for ... Read more

Exchange 2010: Determine Active Sync devices and write to CSV file

The following script can be used to determine all users with Active Sync devices. The data is then written to a CSV file. #Ppath to the CSV file for the export $exportfile = "c:\export.csv" #Name of a mailbox database or "all" to capture all mailbox databases $database = "all" #--------------------- "User;Type;Serial number;Status" | set-content "$exportfile" if ($database -eq "all") ...

Exchange 2010: Approve new ActiveSync devices before synchronization / Policies for ActiveSync

"Bring-your-own-device" has long since become the standard in many companies, perhaps even unconsciously. A correctly configured Exchange Server is very sociable and makes it easy for users to connect any number of devices. Even less experienced users can synchronize their private smartphone with the company's Exchange Server via ActiveSync. However, this is not entirely uncritical. Private ... Read more

Preconfigured load balancer for Exchange test environments

On Steve Goodman's website there is a VM available for free download that contains an almost fully configured layer-4 load balancer based on Ubuntu and HAProxy. It is very easy to set up and is ideal for test environments. Unfortunately, load balancing only works for the ClientAccess role and not for the Hub Transport role. Maybe ... Read more

Exchange 2010: Default settings for the receive connectors

Today, for the first time in a long time, I came across an Exchange server that was configured as an open relay. I actually thought that such configuration errors were a thing of the past. Apparently, however, some people are still making this nasty mistake, so here are the default settings of the receive connectors so that the settings can be corrected. In the default setting there are ... Read more
