I am announcing the publication of my latest article: Email the Easy Way, which is included in ADMIN Magazine #79. This article is a review of iRedMail, a software suite designed to let you deploy your own email server, provided you have a suitable machine to run it on.
iRedMail are very attractive for computer enthusiasts and small business who want to roll their own email solution, without having to contract an external entity to host their email infrastructure. iRedMail is interesting because its free-tier product is sufficient for most small deployments - such as those in which a single firm is using the server. It may run on a number of platforms, including OpenBSD, FreeBSD and most enterprise-oriented Linux distributions.
