  • Setup mail hosting on Debian Squeeze and other distros using postfixadmin

    Postfix is our favorite mail server. We find it’s easy to configure and performs really well.

  • Forwarding email from one host to a new after migration

    It seems a lot of people will move to a new server and want all the old email stuck in /var/mail – its not as easy as it seems to get the email migrated according to google, so I thought i would document it. If you have IMAP available, simply add the new account and…

    I see this particular problem about once or twice a day it seems and probably have for as long as I’ve worked at Rimu. Sometimes customers opt to have their email handled via a 3rd party mail service (google apps, for example).  If the hostname of your server is example.com and you’re trying to send…

    I hate spam.  I really hate spam.  I guess everybody can relate to that.  I not only hate spam, but I don’t like receiving correspondence from some website that made me register to view some content or post a message, some site that that I’ve ordered from or any other place that I’ve had to…
