SCS Computing Facilities Corvid Newsletter

Corvid Newsletter

Over the past few months, SCS Computing Facilities have designed and are implementing several new features for the Corvid e-mail environment. We are pleased to now be able to provide more details about these new features and how they will enhance your e-mail experience.

Automatically cleaning up your SPAM folder

A new feature just released for the Corvid e-mail system is the ability to automatically remove old messages from a folder. This is particularly useful for your SPAM folder; the system can automatically remove messages older than a week (or any other period of time). With this feature, you can still have some time to check your SPAM folder if you missed an important message, but you don't have to take the time to clean out the folder on a regular basis.

If you would like to take advantage of this feature please contact the SCS Help Desk at, or at x8-4231.

New SquirrelMail (webmail) version

SquirrelMail has been the primary webmail interface for the Corvid e-mail system for several years. While functional, the current version of SquirrelMail is starting to show its age. Facilities have been testing a beta version of SquirrelMail for several months in beta. This version will be released shortly to the production webmail server. While this version is similar to the old version, there are several new features that have been added:


-SquirrelMail now supports WebISO authentication. This means that if you have already authenticated to the CS WebISO server, you will not need to authenticate again. You can also log in with either your CS main login credentials, or your CS mail instance credentials. This extra flexibility is great if you are travelling - you can use either password depending on your circumstances.


- In the former SquirrelMail version, if you had a very large mailbox (that is, a lot of messages in your INBOX and/or SPAM folder), performance would suffer. The new version of SquirrelMail has the ability to scale to much larger mailbox sizes without a loss of performance.


- Better navigation. In the former version of SquirrelMail, whenever you viewed a message and deleted it, you were placed back at the main window (message list). This made it difficult to quickly manipulate a large number of messages. The new version of SquirrelMail offers more navigation options, such as "delete and go to next" and "delete and go to previous". This allows you to move through your mail much quicker than before.

Managing your e-mail Folders

Folder Management

Corvid accounts by default have a 2 Gigabyte quota, and even though quotas can be increased (by sending mail to it is important for all users to manage their e-mail quotas. Having large folders not only makes it difficult to find messages but the performance of your mail client will suffer.

Folders that you should manage regularly or automatically are the SPAM, Trash or Deleted, and Junk folders.

  • The SPAM folder contains messages that have been marked by the system as SPAM.
  • The Trash, Deleted and Junk folders are used by your mail client to hold messages that have been either deleted or marked as Junk by your client.

You should periodically review the contents of these folders (especially your SPAM folder) to clean out messages that are no longer needed. You can typically remove anything older than one week in this folder or have the system do it for you automatically. The Trash, Deleted and Junk folders should normally be emptied when you are about to exit your mail client.

Also, with some e-mail clients (Thunderbird, for example) you can detach an attachment from an e-mail message and store it in your file system. The original message remains in your mail folder for your reference, but you can free up the space taken by the attachment in your mail.
