Great project, thank you Josh. I am donating to your project and will also offer $100 to help fund the creation of an apt-get deb package, if you or anyone here would like to commit to creating it.

I run mail servers with Postfix and much of the same setup, to enable custom domains, scriptable responders, message tagging, and the like. Using apt-get to install Mail-in-a-Box would be wonderful.
