General information

NCF provides every member with a personal email address. NCF email addresses are simply a member's account ID (eg., 'ab123') followed by '@ncf.ca', for example, 'ab123@ncf.ca'.

Optionally, you can arrange for an email alias, for example, 'jsmith@ncf.ca'.

Important: If you already have an email address and do not plan to use your NCF email address, be sure to tell us, using Change Preferences at the bottom-right of the StartPage. NCF needs to be able to reach you about your account.

Receiving mail

Incoming email for you is stored on NCF's computer until you ask for it. There are two ways to receive email:

Using NCF WebMail (browser-based)
All you need to use WebMail is a web browser connected to the internet (eg., home, office, library, internet cafe, anywhere in the world via internet). No set-up is required. You read and send mail from the browser using the Zimbra interface and your mail is stored on an NCF computer. With WebMail, your email stays on the computers at NCF and is backed up there, too, to protect against loss.
A disadvantage of using WebMail is that you have to stay connected to the internet while you are reading and composing your email.
Using an email client (on your personal computer)
Email client software allows your email to be transferred to your computer and then read there. The size of your mail archive can be as large as your hard drive.
A disadvantage is that your mail is only accessible while you are at your own computer.

In the past personal computer-based mail clients were dominant, but in recent years the trend has been away from mail clients and towards server-based webmail, because of the convenience of being able to access the mail from any browser anywhere, even from phones and hand-held devices, as well as automatic back-ups.

Zimbra Limits at NCF

There are several limits you may encounter in your use of Zimbra.

  1. Mail storage size - members are allocated 1000MB of storage. This contains all the mail and briefcase data. Members must manage their space within that limit. See how to check your storage space.
  2. Mail message size - a maximum of of 56MB per message is allowed. The actual file size of the attachment is 20-30% less as special encoding is required to send it via email. If you have large files that you wish to share, there are a number of other file sharing approaches that may be better than attachments. One of those is using the Zimbra Briefcase - see Zimbra: Briefcase.
  3. Sending rate - NCF limits the rate at which members can send out email to protect against spamming. A limit of 200 messages over a 4 hour span is in place. If you have large distribution lists that will exceed this, please contact the office - we have a solution.

NCF Webmail

NCF Webmail allows you to compose, send, receive and manage your email using any browser. It is the easiest way to send and receive email while you are away from home. Your mail stays on the NCF's mail server. To use it all you need is a web browser and connection to the Internet.

You can try WebMail by going to the StartPage and clicking on 'Get your NCF WebMail'. There is nothing to install on your computer.

Up to 1000 MB of email can be accumulated and stored in your WebMail Inbox and folders, as of early 2017. NCF's storage capacity increases regularly as facilities are upgraded.

The NCF Webmail system runs the Zimbra mail system. For an overview of the benefits of Zimbra, please visit the Introducing Zimbra page.

Mail Clients (Mail readers)

Some common current mail clients, all available for download free of charge, are:

If you do not have a mail reader, you can download one for free. Once it is installed on your computer, you need to configure it so it knows from where to retrieve/send your email.


  • Microsoft Outlook Express is very outdated, has serious security problems, is no longer supported by Microsoft and is not recommended by NCF. See this article for more detail on why you should replace it.
  • Microsoft Outlook is commercial software and comes with Microsoft Office.

Setting up a Mail Client or Mail Reader

Modern mail readers are pretty easy to set up. Typically you just need some of the information in the 'Quick Facts' box above.

For step by step instructions, click on your mail reader below:

For information on whether you should set up your reader for POP or IMAP see What's the difference between POP and IMAP?.

Keep in mind if you use an email client that it will not retrieve your yellow mail that the spam filter saves there for you.

I can receive email, but I can't send! (Relay Access Denied)

If your mail account appears to be setup correctly, but you are having trouble sending, it could be that you don't have SSL and authentication enabled.

Spam Reduction

Customizing SpamFilter

Regardless of how you read your mail, you can use NCF's SpamFilter if you have problems with spam.

You can view or change your SpamFilter settings by going to the StartPage, and clicking on SpamFilter set-up under 'Email' in the left column. There is information on that page about how SpamFilter works and Frequently Asked Questions on customizing SpamFilter.

There is also a short video on setting SpamFilter options.

Blocking Specific Email Addresses

Spam can be difficult to stop as spammers are relentless, and can often send messages from many different emails, making it much more difficult to stop.

If the undesireable messages you are receiving are coming from the same address, it would be best to add a mail exception on your spam filtering page here to ensure the offending address is blocked from sending you mail in the future.

Simply enter the offending email into the “Email address” bar and enter “Classification” as “Red” to ensure this address will be marked as spam and not be delivered to your mailbox in the future.

Using Yellow Mail

NCF provides a facility to screen mail items that your SPAM fileter settings have found questionable before the mail enters your Zimbra inbox. This is called yellow mail. You can see a short video [here] on how to use it.
