I set up a Postfix server on my Ubuntu VPS and it works for sending email from the mail utility in the command line. I set up SPF records, DKIM, pretty much everything I could read about. However, I'd like to be able to send and receive email without SSHing into my box each time.

When I try to set up my server (borogov.es) with my mail client, and I use "mail.borogov.es" as my outgoing mail server, I get "Server not responding." I feel like this is an access issue of some sort, but I'm not sure.

I'm not running a firewall. What could be going on?

I have a cloud server hosted at Rackspace, and they use Xen Server hypervisor. I was running Ubuntu 12.04, and really messed up by attempting to do a release upgrade manually.

The hypervisor apparently doesn't get along with the changes made to GRUB (I think; there could be more) and thus does not reboot; it gets stuck at the initramfs stage of booting:

I've been speaking with a tech for a long time. We're rather undecided on what to do; would it make sense to provision a new server, grab that kernel / GRUB config, and drop it on the current server? Or to try and roll back the changes / downgrade?

If you have any suggestions, they would be greatly appreciated.

I just set up an IRC server on my laptop for the local network. however, ChanServ and NickServ don't seem to be installed/available. How might I get them?

How would I go about telling my web server (Webfaction) to just run a python file and let it keep running forever? Someone told me I should use cron but I haven't found any good material on how to run it once, and have it not stop.
