MyMail @ Mines

What is MyMail?

MyMail is part of a service partnership between Mines and Google. This partnership enhances your Mines email capabilities, and enables you to use the popular suite of Google applications (including Google Docs, Talk, and Calendar) directly from your MyMail account. Once created, you can access your Mines email through a variety of email clients, mobile devices, and Google’s Gmail interface. Your email data is stored on Google’s servers. MyMail is typically used by Mines students. Staff and faculty use Exchange email.

Frequently Asked Questions

1. When will my MyMail account and @Mines.EDU address expire?

Please see this ITS FAQfinder entry ( for more details. In short, your account is eligible for removal as soon as you are no longer a registered student, faculty, or staff.

2 Can I access my mail from the internet? What are the IMAP / POP server settings for MyMail?

You can access your student email at from practically any computer with a web browser. Log on with your Mines MultiPass credentials. You can also access MyMail with an email client program like Thunderbird, Mac Mail, or Outlook — any program that supports the IMAP or POP protocol.

You must enable “less secure apps” in for your MyMail mailbox when using IMAP or POP (see instructions, below).

With a POP client your email is moved from the ITS MyMail server to a local computer and no longer backed up on Mines servers. With an IMAP client your email is accessible remotely, but is stored and managed on the server. Most popular POP email client programs also function as IMAP clients. Although there are advantages to using each, we recommend that you use IMAP for flexibility of access. You should use POP only if you fully understand how it works and the ramifications of where your mail will be stored and how it can be accessed.

Further details: Before you can send or receive email via POP or IMAP, you need to log on to and enable the proper protocol by clicking on Settings (a sprocket icon) -> Forwarding and POP/IMAP.  Enable POP or IMAP, as appropriate and save your settings.  The “allow less secure apps” option will also need to be enabled for your account.  You can find that option at  Additionally, you will need to generate a new password that is only used for POP and IMAP connections to MyMail.  See more about MyMail at further information on resetting passwords.  Once your password has been set, use the following settings to access your MyMail account using POP or IMAP.

Less Secure Apps must be enabled for POP and IMAP to function.  You can enable this function at after logging into your MyMail account.

3 What is my address? Is it or

Your official address is your address. Email going to your address will automatically be forwarded to MyMail as long as you are a registered student. Once you are no longer a registered student your MyMail account will be removed along with the forwarding. What does this mean? There is no need for you to change your existing email address on documents, correspondents’ lists, etc.

4 What is the advantage of using the address?

Using your address will allow incoming messages to be routed to on campus servers then routed to your MyMail mailbox. This enables you to have emails scanned by the ITS spam filter. This also allows whitelists or blacklists to be used when combined with an ITS spam filter quarantine account. Using the address bypasses all ITS servers and routes mail directly to Google. For those eligible for a “Mines Email Forever” account, the address will cause minimal disruption.

5 What is the advantage of using the address?

Using your address will bypass the ITS spam filter or any other on campus servers and will deliver mail directly to Google’s servers. This will bypass any whitelists or blacklists configured in a ITS spam filter quarantine account.

Configuration settings and instructions can be found on the “Forwarding and POP/IMAP” settings tab in your MyMail account settings. Note: These settings will be specific to Google. You will not use or to check mail. Settings can be found on Google’s help page under “Other ways to access Gmail.” Keep in mind your username for IMAP or POP access will be your full email address such as and not as the help pages imply.

10 What are the attachment limits for MyMail?

Attachments can be no larger than 20 megabytes in size after transport encoding. Typically attachments 15 megabytes and smaller will encode and be delivered to your MyMail mailbox without any problems. Attachments between 15 and 20 megabytes may be larger than the allowable limit after it is encoded for transport between mail servers. It is good practice to keep messages under 15 megabytes in size.

11 Are zipped attachments allowed?

Yes, with some provisions:

  1. Do not contain executable files, which are security risks and not permitted as attachments or within archives.
  2. Are less than the maximum attachment size limit.
  3. Are not password-protected or encrypted.
12 Are PGP encrypted attachments allowed?

Yes. As long as they are less than the maximum attachment size limit.

13 What is the quota size for MyMail?

MyMail quotas are increasing daily. As of this writing the quota for your MyMail account is over 7.3 gigabytes.

14 If I permanently delete messages or Drive data can they be recovered?

No! Once you delete a message by clicking on the “Delete Forever” button it is no longer available and cannot be retrieved under any circumstances. Do not click on “Delete Forever” unless you really mean it. Do not enable POP unless you understand that it will remove messages from the server when your client connects.  Drive documents cannot be recovered if they are deleted.  Do not delete a document unless you are sure it is safe to delete.

15 Does MyMail support mobile devices such as the Apple iPhone or RIM Blackberry?

You may need to enable IMAP or POP if you wish to use a mobile device with your MyMail account. ITS advises IMAP since messages are kept on the server and reduces the amount of memory required of your mobile device. The IMAP protocol works great with the Apple iPhone. (At this time PUSH email is not available, however.)

16 Can I sync my MyMail calendar and contacts with my mobile device?

Yes. Follow these instructions on the Google Sync help page for iPhone support. Other phones can be found here.

17 Will I see advertisements like I see with my regular Gmail account?

No. Advertisements are disabled for the domain, however, accounts will have ads enabled.

18 I see tickers above my inbox. Can this be disabled?

Web clips can be disabled by choosing Settings > Web Clips. Then uncheck “Show my web clips above the Inbox.”

19 How do I reset my MyMail password?

Visit If you have previously set up your challenge questions, you can quickly reset your MultiPass password. If you have not set up your challenge questions, please visit the Mines Service Center (CT156a) or submit a support request via Mines Help Center for assistance.

IMAP/POP Passwords
There are two passwords associated with your MyMail account.  The first password is your web login password.  This password is also shared with ADIT, Trailhead, and Multipass systems. The second password is stored with Google and is used to access your MyMail through IMAP and POP mail clients. Both passwords can be reset through the Identity self service login page at Click Manage Your Account and login with your current password. “Change my password” will reset your Multipass, ADIT, Trailhead passwords. “Change my Google IMAP/POP password” will generate a new password to be used only when accessing mail through MyMail and POP or IMAP. You can not generate your own POP/IMAP password.

20 What about backups? Should I be backing up my messages?

ITS does not backup or maintain any copies of data associated with your MyMail account. This includes messages, contacts, gDrive,  or calendar information. It is your responsibility to keep copies of the data you believe is important in a secure place other than in the MyMail Google cloud. There are various programs that will backup Google mailboxes. Do a Google search for “gmail backup” to see what is available. Another option is to enable IMAP and copy messages from MyMail to local folders stored in your mail application. You will still need to perform regular backups of the machine your mail application is run on.

21 How do I automatically filter and delete a message with a particular phrase in the body?

Here is a little How To document on creating a filter by e-mail address.

22 When I send e-mail from my account to my address it doesn't appear in my Inbox.

When a message is sent to your address from the address it forwards to, your MyMail address, Google will discard the message as a duplicate. The original message is still found in your Sent Mail folder.

23 How do I logout of MyMail? / Why doesn't the Sign Out button work?

MyMail web logins are now handled by Mines servers.  When you sign in using the MyMail login page, our servers tell Google that you are a trusted user and should be allowed to access your mailbox. Google does not store sign in cookies on your machine since we were the ones providing authentication. Instead, we store our own cookies in your browser cache. Because of this, the hard coded “Sign Out” button that is a part of all Gmail accounts will not work for MyMail users. You should EXIT or QUIT the entire browser program to properly sign out. Closing the browser window or tab is not enough. You must QUIT or EXIT the entire browser application.  Once the browser quits, the cookies will expire immediately. For browsers that are left open, the cookies will expire sixteen hours after login.

It is extremely important if you are using a public computer such as a library kiosk, Internet cafe, or even a roommate’s computer, that you QUIT the browser and sign out of the computer.  If you fail to do this it is possible someone else may be able to access your account.

24 When trying to login I get "Login Failure: Cannot locate KDC."

For the Username field on the login page, enter only your username — in all lower case — not your email address. (For example, enter only jdoe, not, JDOE, or JDOE@MYMAIL.MINES.EDU.) If you enter your email address or use upper case, you will get the following error: Login Failure: Cannot locate KDC
