In the field, at hotel rooms, in VM environments, Demo setups and many other situations your are in the situation that something needs to be able to send an email and installing an Exchange Server at that time might be very wrong. So I have been using a really nice SMTP server that basically accepts anything, with any kind of settings and that has the ability to present all these mails in a single view. Extremely “handy” to have. Download it from http://smtp4dev.codeplex.com/
I use it to test OSD scripts, Orchestrator runbook jobs and things like that.
