Notes on the January/February 2010 Server Migration

The following are notes regarding the mail and web server upgrades taking place in February 2010. It is primarly of interest to those who had accounts prior to this upgrade. If you have questions on the matter, please contact hostmaster at taiga.ca.

Changed URLs

Various URLs have been changed. Generally most stuff is under www.taiga.ca now, rather then mail.taiga.ca or elsewhere. Update your bookmarks.

Updated Certificates

Various SSL certificates have been updated and/or created anew. These include:

Updated SSH Host Keys

Some SSH host keys have changed. In particular, if you are using sftp or scp to update your web pages, you may see a warning or error about a new key. You may have to delete your old host key to get rid of the warning or error.

Tanana Email Addresses

If anyone is publishing an email address of the form USERNAME@tanana.taiga.ca, please stop doing so. That address will stop working. You should be using an address from one of the officially hosted domains. If you in fact have need of a taiga.ca address and USERNAME@taiga.ca bounces, contact Jim B. and ask him to have Devin set it up for you.

Mail Filtering and Forwarding

This section applies to you regardless of whether you are using webmail, accessing the system directly through a dedicated email client (Mulberry, Outlook, Mac Mail, Evolution, whatever), or forwarding your mail to another address.

Your existing filtering rules should have been migrated forward. However, please examine them (by logging into the Horde web mail system) and verify that they are correct (especially if you modified your rules before the migration but after 09 Feb 2010).

The Spam Filter rule is a shortcut for redirecting possible spam to an alternate email box. See the Mail Filtering, Forwarding, and Spam Reduction page for details.

For those of you who were deleting mail outright based on the spam score, the rule is now (usually) called Discard Spam. Some people have a pretty high score for this rule. You may want to consider dropping it down, based on what you're seeing in your spam folder (view the message headers to see the score). A score of six or seven is probably reasonable, but that's up to you.

On the old mail server, you may have noticed .forward files in your home directory. These are no longer used; don't try to create one to do mail forwarding. Instead use the supported mechanism.

On the old system, when using .forward files, the filter rules were not consulted. Since forwarding is now done via filter rules, it is strongly advised that you discard high-scoring spam before forwarding. This lessens network load, and minimizes the chance that this mail server will be marked as a spam source by other servers.

If you are forwarding to multiple addresses, the filter rules will allow you to continue doing so; just enter one address per line.

Webmail Preferences

Unfortunately, there is no good way to migrate your preferences from the old webmail system to the new one, so you're asked to go through your preferences before you start sending mail. Most of the default settings are probably fine, however you will still have to perform a minimal configuration before the system will permit you to send mail through the web interface.

Migrating Your Webmail Address Book

If you are using the address book capability of the web mail system, we ask you to migrate over your address book between the old system and the new yourself. (The two systems are quite different in their implementations and unfortunately there is not a good way to do this in an automated fashion.) If you have a more recent address book on your home machine, PDA, or whatever, you may wish to import it into the new webmail system directly instead of grabbing data from the old webmail system.

(There are other data source synchronization options that we may investigate in the future as well, described at Syncing with Horde Applications. If you have any interest in this, please let us know by sending an email to postmaster at taiga.ca.)

In order to migrate your address book, you first need to export it from the old webmail system, then import it into the new one.

In order to export your address book from the old system, perform the following steps:

  1. Log into the old webmail system at https://mail.taiga.ca/horde-stable/

  2. Go to the bottom of the screen and click on Address Book.

  3. Click on Browse at the top left of the screen. If you don't see any entries, you don't have anything to migrate (and you're done).

  4. If you do see address book entries, then click on the Import/Export icon at the top of the screen.

  5. In the bottom half of the screen, you'll see a section titled Export Address Book. Ensure that Comma separated values and LDAP Addressbook are selected, then click on the Export button.

  6. Save the resulting file turba.csv on your local computer.

  7. Log out of the old webmail system.

In order to import your address book to the new system, perform the following steps:

  1. Log into the new webmail system at https://www.taiga.ca/horde

  2. In the left menu, expand the Organizing tree item.

  3. Under Organizing, click Address Book.

  4. Click on the Import/Export icon at the top of the screen

  5. Under the Import Address Book section, ensure that Comma separated values is selected.

  6. Optionally, click on the checkbox to replace the existing address book with the imported one. If this is the first time you've tried this, it will have no effect.

  7. Click on the Browse button and select the turba.csv file that you saved from the old webmail system.

  8. Click Next.

  9. At the Import, Step 2 page, click Next.

  10. You should now be on the Import, Step 3 page. There is not a perfect match in address book configurations between the old and new webmail system. However, you can move over most of the information and then edit it in the new address book later:

  11. Click Next

  12. You should now see a yellow bar near the top of the screen that says CSV file successfully imported

  13. In the left panel, click on your personal address book icon (the words may be truncated), which is right above the Search icon. You should see the imported entries.

  14. Various entries may show doubled last names. For example, Nicole Kidman may show up as Nicole Kidman Kidman. To fix these entries, click on the edit icon (or click the checkbox and click on the Edit link) and correct the First Name field.

    While you are updating that entry, go to the Location tab and modify, if necessary, the home address. (If you had a home address in the old webmail address book, it will all be under Home Street Address instead of broken up into its constituent fields.

    Click Finish when you are done.

Updating Web Sites

For those of you with hosted domains or personal web pages, the site to which you need to connect to via sftp has changed. You should now connect to www.taiga.ca.

If your sftp client complains about a changed host key for the given IP address, you may need to delete the old host key.
