I installed two Linux/Postfix MX's for my Imail Boxes using address_verification and it has helped tremendously with dictionary attacks.
I also moved my kill.lst contents and some trusted reverse DNS tests to these MX's off-loading the Imail boxes. I used Len's config files as references. This made setup much easier. Used Redhat Fedora Core 2. Its all GUI, and Postfix is simple text configs. A very cheap and easy solution. Thanks Postfix, Linux, and Len!

We just enabled a Linux/Postfix box in front of imail yesterday. No Imgate here, just a postfix setup with mailscanner, ClamAV for virus scanning and Spamassasin. The load on our Imail box when down from an constant 60% down to spikes of 10% usage. On Mon, 12 Jul 2004 14:36:16 -0700, A.
