I’ve been busy preparing for a transition of many co-workers to a Microsoft Exchange service lately. Until that migration occurs, we use a web interface and/or Thunderbird to interact with the IMAP mail server. For context, I am a big fan of Thunderbird and prefer it over other similar desktop clients. Much of my time recently has been spent figuring out Outlook instead of using Thunderbird and keeping my ear to the ground for related mail applications. That being said, I still managed to catch Postbox in the beta stage and I have to say I’m quite impressed with the modifications they’ve made over Thunderbird.

Spamihilator sits between your email client (Outlook, Thunderbird etc) and the internet and examines every incoming email in order to identify spam.
