Moving – mail

I finally moved the mail service to Google Apps.

I looked long and hard; and even thought about moving the mail to a hosted environment for a few months.

Finally I tested out the google hosted email service – and it looks pretty good.

On the positives:

  • fully hosted, in the cloud service
  • backup, restore and availability are all looked after
  • anti-virus is included
  • anti-spam is fantastic
  • web mail, POP and IMAP services
  • 6GB ++ per user
  • it’s FREE!

The only downsides are around:

  • questions about privacy
  • no SLA on the free service

At the end of the day this frees up two servers running multiple services; and saves me the backup and availability headaches.

  • IPCop with Copfilter
  • Spam Assassi
  • Clam AV
  • eDirectory/Novell NetMail
  • It should also give family a better experience (webmail/POP to a google datacenter rather than to my server) and give me more bandwidth to play with.

    Moving IT infrastructure

    One of the things I get to plan is moving the IT infrastructure. Pulling the plugs and moving the servers is the easy part; but what about the DSL, static IP, mail, MX records, DNS..

    I think I’ve found a solution for the mail (hosting the mail server) and the DNS is already moved out and re-hosted on two different DNS servers. Might be just web-mail for a week or so – but that’s more than enough.

    The blogs and photos will be offline while the servers are on the move – the rest of the infrastructure is just internal stuff; NAS, print, authentication etc.

    Any hints and tips from those that have moved SLES and Windows 2003 servers before?

    Airtunes and 802.11b

    I’ve got three Apple Airport Express units to stream music around the house. They work really well – and when used with Rogue Amoeba Airfoil I can play pretty much any music now via Airtunes.

    However… I’ve had a sticky problem for the last year – 50% of the time iTunes or Airfoil just can’t see all of the Airport Express boxes. I’ve spent a lot of time researching Bonjour (aka Rendezvous, zero touch, multicast DNS) and doing packet traces. No joy. Everything looks fine; the multicast DNS is working fine over 5353; the radius is within limits; firewalls are non-blocking; the data is not crossing a router. I was stumped.

    Tonight I think I fixed the issue. As part of de-cluttering for the impeding house move I took my last 802.11b device off the wireless subnet and bumped the configuration to be exclusively 802.11g. Instantly everything started working.

    So in summary: Airport Express, Airtunes, iTunes and Airfoil really work well on an exclusive 802.11g network.

    Hope this helps someone else.

    SMTP, hotels, SMTP proxies and secure SMTP

    Most hotel internet connections use an outbound SMTP proxy to store and forward email.

    I’m never happy with that – it means that my mail could be delayed/lost/corrupted/tampered with/read on the way.

    [Note: I know – SMTP is SMTP – it’s not secure; it’s like writing a postcard – but if I can avoid that proxy – it’s one less set of eyes..]

    I’ve now configured Thunderbird to connect to a high port that’s NATted back down to port 25; I’ve also forced TLS to the mail server.

    In theory that should keep my outbound mail (or really internal mail that only sits on my web server) a bit safer.
