Google Apps

We have been working over the last few months to set up and deploy Google Apps to all of our various e-mail users at work. In case you have never heard it before Google has bundled many of their online offerings (Gmail, Google Docs, Google Calendar and Google Sites) into a company branded version that can be aliased with a custom domain name. Since we are a non-profit organization Google has given us 3,000 accounts for free!

Gmail interface - Work e-mail address!

Who could say no to an offer like that?  We are looking at the collaborative possibilities of having over 2,000 active accounts in one Google Apps system.  Our current e-mail infrastructure is a mixture of Microsoft and open source products.  We started off with a small Windows e-mail server and have grown over the years to support over 2,000 mailboxes.  We decided to go with a few different solutions for different segments of this user base over time as needed.  In the end we have five servers all working together to run and manage our communications infrastructure.  It’s a mess.  It’s also rather burdensome to administer.  Enter Google Apps with its unified management system, familiar end user facing interface, compelling and easy to use overall setup and the choice to switch is fairly easy.  We started off with about 10 beta users and then migrated the entire Communications and Information Technology offices.  Once we were convinced that the system was working well we began the roll out process to internal staff.  We are up to about 150 active accounts now but we have a long way to go.

What are some of the major benefits of switching to this system?

  • We reduce our support surface from five different servers, operating systems and mailbox formats down to one integrated interface.
  • We will have access to an whole host of collaborative tools that was not previously possible.
  • Our end users will have reduced confusion.  Many times they call us and have forgotten which server they are hosted on (so do we!).
  • We don’t have to write documentation anymore.  We just link from Google’s support website!
  • We no longer have to constantly maintain our e-mail gateway anti-virus and anti-spam scanners.
  • Microsoft Outlook integrates into the Google Apps system.  We have a good number of users that wish to continue using Microsoft Outlook instead of the web interface.

Google Apps allows a custom logo for each organization.

What kind of things can we do with this new system?  Here’s a few ideas:

  • Easily share user calendars so that co-workers may know when they are available for meetings.
  • Set up shared documents, spreadsheets and presentations for collaborative work within offices.  These documents can also be shared with the entire Conference or with all visitors to our website.
  • Set up Google Sites for project based collaboration (rather than just individual documents).
  • Easily manage e-mail and make use of the labeling system for filing away old messages for later retrieval.
  • Easily set up a system group that I can use to communicate with all of my end users simultaneously.

What other ways can we use this?  We are concentrating on the migration from our existing systems now and will move on to feature implementation later.  I’m curious to hear other ideas as to what we can actually do with this system once we have everything in place.  I’ll post updates as we move along in the implementation process.  We are very excited about all that we can do with this new system!

E-mail Will Be A Hit, I Can Feel It!

The Dangers Of Not Paying Attention

This blog post from the Internet Storm Center over at SANS highlights the need to pay attention to the setup of your server systems.  We aren’t using this particular blacklist but it still highlights the point.  This is why I spend so much time following mailing lists and keeping up with my feed reader.  This kind of thing is easily avoidable.

Aaron let us know about a discussion thread on the NANOG mailing list about issues with the blackholes.us DNS block list (DNSBL):

The issue is the maintainer of the blackholes.us DNSBL shut the list down some time back and  the IP address space that the DNS servers for it were on was given back to ARIN.  That address space has since been re-allocated to a new company and they are getting tired of the continual inbound DNS queries to the IP address of the old server.  Apparently they have now stood up a DNS server to answer those queries with a wildcard record that effectively returns “yes, the IP you are inquiring about is a spammer”.  As a result, lots of mail relays that are still configured to do lookups against this DNSBL are now being told that everyone on the Internet is a spam source.

According to this post in the news.admin.net-abuse.email Usenet newsgroup, the DNSBL was shutdown 2 years ago.

If you are an email administrator, please check your RBLs to see if you are still submitting queries to blackholes.us and remove it from your configurations if you are.  You should also review any other RBLs you are using to ensure that they are still in operation as well.
