Yes, a simple topic. However, although regularly upgrading an outdated engine is a known necessity for those systems running ClamAV as their virus scanner, there’s not much, even no clear document expressing such an easy and common task directly without getting things complicated. We wanted to touch on this subject in order to state the steps clearly. We also thought that hereby it might give a good chance to meet the popular portupgrade tool, for especially those who struggle to manage their ports and packages on production systems.

Dkim-milter is No Longer Available, How to Use OpenDKIM Instead
When we implemented DomainKeys Identified Mail (DKIM) with Postfix on FreeBSD, we had used dkim-milter plugin. However, it seems that dkim-milter has expired and recently it has been removed from the ports tree. Consequently, we’ll also move to OpenDKIM which is in fact claimed to be bug free compared to dkim-milter. Installation and configuration approach isn’t going to be much different from dkim milter at bottom, anyway we wanted to give the whole process step by step here. Let’s get to work by first updating our ports tree if it’s stale.

Disabling Outgoing Spam Scans In Maia Mailguard
There may be two leading reasons of trying to disable outgoing spam scans in a corporate email system; The risk of overwhelming the system resources and the fear of false positives. Regardless of which one is yours, doing so causes another drawback that one of your local machines can someday become the origination of spam if it is compromised by a virus or a skilled intruder. If you’re managing relatively a small, individual mail site which is strictly under your control and you truly master what enters and leaves your network, it may be an acceptable approach to gain the advantage of not worrying about the outbound email traffic. If you ask us, using the reporting and learning capabilities of your system is more feasible than simplifying things in an old school way.

Maia Mailguard 1.0.3.rx Installation and Configuration on FreeBSD. The Differences.
Last year in September, we published “Maia Mailguard Setup On FreeBSD” as the sixth article of the compelete Postfix email system guide. Overlapping the new release of FreeBSD, new Maia version also has some major changes in its layout and mechanics. Therefore, we decided to post a quick essay over the new installation and configuration routines of Maia Mailguard, yet more by testing it on FreeBSD 9.0 platform. But please keep in mind that here we’ll only give the differences between our original “Maia Mailguard Setup On FreeBSD” article, and the achievement of this setup is bound to previous Postfix system component setups in one way or another.

Enabling Roundcube Vacation Removes Actual PostfixAdmin Aliases
PostfixAdmin is a GUI which we use frequently to manage our users and domains in a Postfix system. Creating email aliases and “Forward only” redirections are the most regular tasks we carry out while managing it. Likewise, Roundcube is a free, convenient solution for the webmail demands and the vacation plugin is the indispensable component for enabling users to manage their own “Out Of Office” replies. Complete step-by-step setup guides can be found here for PostfixAdmin and here for Roundcube.
