How to mess up mail delivery

Here’s something I just learned: If you are running dma(8), /etc/dma.conf will contain MAILNAME.   If your email server is somewhere else, but you set MAILNAME as your domain – dma will deliver locally.

I had /etc/dma.conf set with MAILNAME shiningsilence.com – so dma kept delivering overnight periodic results to root, which was aliased to justin@shiningsilence.com in /etc/mail/aliases and so it was delivered to ‘justin’ locally on the machine.

Changing MAILNAME to www.shiningsilence.com – the host you are reading right now – fixed the problem.  Now, whether this was an automatically set config or something I misconfigured some years ago… I can’t tell.

NVMM lands in DragonFly

Aaron LI’s added NVMM, hardware acceleration for virtual machines, to DragonFly.

The version of qemu in dports is not set up to support this, yet.  Until then, you can download a prebuilt version.

Since NVMM originated on NetBSD, the NetBSD documentation page for it describes how to use it quite well.  There’s a man page in DragonFly for it too, of course.  There’s even basic machines to try.
