iGEL's questions

I want my server to notify me about pending security updates. But I don't want to get notifications about all available updates. How can I do this?

I try to set up a maintenance page for my rails app, using this snipplet.

error_page 503 /system/maintenance.html;
if (-f $document_root/system/maintenance.html) {
  return 503;
}

This works as far as the presence of the maintenance.html causes the webserver to return a 503. But it returns the minimal nginx default error_page, not my maintenance.html. Why?

nginx 1.0.12 on Ubuntu 10.04 LTS

I would like to reject mails to a certain address with a custom message. Mails to other non existing addresses should be unchanged. How can I do that? I'm using Postfix 2.7.0 on Ubuntu 10.4.

Background: My websites sends mails to my users, and so far, my personal address is used as the sender. I would like to change this to a noreply@... address, but since the users reply quite often to these emails, I would like to send them a helpful reject message.

Thanks!
