Converting All Your MS Outlook PST Files To Maildir Format One of the challenges you may face when converting an office from Microsoft Windows to Linux is that many people archive their e-mail in PST files. There are PST tools available, but most of them are commercial, since the PST file format is closed and protected by Microsoft. There are several non-commercial methods to achieve roughly the same goal, and in this tutorial we use IMAP (more specifically, courier-imap) to convert all our e-mails from PST to the Maildir format. The advantage of this approach is that you also lay the foundation for a new mail system, with all your old e-mails already imported the day you switch over.

Introducing Remo - An Easy Way to Secure an Insecure Online Application with ModSecurity Say you have a nasty application on your Apache webserver that has been installed by some jerks from the marketing department and you can neither remove nor patch it. Maybe it is a time problem, a lack of know-how, a lack of source-code, or possibly even political reasons. Consequently you need to protect it without touching it. There is ModSecurity, but they say this is only for experts. A straightforward alternative is Remo, a graphical rule editor for ModSecurity that comes with a whitelist approach. It has all you need to lock down the application.

How To Block Spam Before It Enters The Server (Postfix) The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Let’s say somehow we lost the usernames and passwords of the mail server. In this case the admin has to manually create all the users and then change the passwords for all the users. Tedious job. Let’s make our life easier.
