Introducing psFetch


25th September 2008 NAMOS,Systems 0 Comments
psFetch is my latest project and is a Powershell cmdlet that communicates with various Repositories on the Internet to find what you are looking for and easily download and install them to your machine. The cmdlet itself is written in C# and utilises a centralised LAMP backend as a repository and director. Upon install psFetch will create a custom shortcut on your desktop which includes the psFetch cmdlet as one of the default set of commands available without having to use add-pssnapin each time.

Dealing with Massive Spam Levels In Postfix


1st September 2008 Email,NAMOS 0 Comments
Recently I encountered a situation where a vanilla install of Postfix had been targeted by what appeared to be a Spam Botnet. Bizarrely this server was what you could call an 'Edge Server' but it didn't have any AntiVirus or AntiSpam to be honest it was pretty useless. There were three issues to clear up. First there were 2,435,239 emails from the Botnet destined for a domain that was no longer hosted on the 'backend' server. Secondly none of this email was being Spam checked and finally the massive queues meant that the 568,372 legitimate emails stuck in the queue were being delayed by ...
