It recently hit me that upon setting up the email/web server for the local Linux and Perl groups, I never added a backup MX record to the DNS entry. Which would be a problem this weekend due to scheduled downtime of the datacenter it's being hosted in.

Andy was kind enough to offer their Querx.com server (what in the world is a Querx?) for backup email.

I just went to setup the secondary MX, and realized I never bothered to add *any* MX record. Apparently, email can still get delivered without any MX records listed. Every person on the CPLUG and HPM mailing list has been doing it for three months :-)
