Every staff, faculty and student at GGSE has a GGSE email account of the form ITG provides email services via IMAP and SMTP. You can access this email account via Webmail from anywhere with a web browser and an Internet connection. You can also configure most email clients to work with your GGSE account. We recommend that you do use a good email client like Mozilla Thunderbird to fully take advantage of our mail services.


Terms, usage and limitations

For a complete list of our most current usage terms, please see our IT Use Agreement.


Every user at the GGSE has an e-mail quota, or size limit, for their email account. Every piece of mail and attachment in every folder in your account counts against your quota. The current quota is 250MB, For Student Accounts. Here are some methods for checking your quota:

Attachment Size

The GGSE webmail will allow attachment sizes up to 5.12MB while map clients, such as Thunderbird will allow an attachment size of 18MB, either sending or receiving. If you are having trouble sending an attachment that exceeds this size consider compressing, (using winzip to make a .zip file) before you attempt to attach and send the file.

Mozilla Thunderbird

In Thunderbird, you can use the DisplayQuota add-on. Most of our Thunderbird users already have DisplayQuota, but if you don't, you can download DisplayQuota here. DisplayQuota will show your space usage in the bottom-right corner of Thunderbird as a bar and percentage.


In Webmail, you can follow these instructions:

  1. Log in to Webmail
  2. Click Options along the top
  3. Look down the page for the word Quota in bold text

Managing your quota

  • Use an email client like Mozilla Thunderbird to download/backup e-mails to your hard disk using Local Folders. With copies of your mail on your own computer, you can remove mail from the server to reclaim space.
  • Empty the trash
  • Sort your email by size, download the attachments from the largest emails, then delete the ones you don't need.
  • Clean up or empty your Sent folder.

Account life

Once your term with the GGSE has ended, you account may remain active for a pre-determined time period. The period may vary, but generally follows these rules:

  • 6 months after graduation for students
  • Immediate deactivation for staff
  • Negotiable for faculty

Features and services

Depending on which email client you use, the features which you are able to access will vary. ITG offers the following mail-related features and services to all GGSE users.

Account lockout

If you fail to authenticate several times via Webmail, your account becomes "locked" and you will be unable to log in for a set time. Attempts to log in during a lockout will reset the lockout timer and extend the lockout.
