Introduction to email
- Your complimentary NC Wireless email service is always ready to accept messages using an email client such as Microsoft Outlook or Apple Mail or Webmail.
- POP and IMAP are the two most common email protocols on the internet. They both allow an email client to communicate with your services, but they do so in very different ways.
- If you wish to add a new email account please LOG IN to your customer account portal and create a new Support Ticket requesting an address.
How POP works
POP (Post Office Protocol) is the older of the two methods for mail retrieval. In the most basic sense, POP simply grabs emails from your server and downloads them to your email client.
When using POP, emails are deleted from the server and will not be available if you attempt to access your mail from another email client or webmail. Some email clients offer a feature to leave a copy on the server. We have seen many email issues from this feature being used improperly.
Also, on any NC Wireless address, junk mail may be routed into a Spam Folder which is accessible only to Webmail and IMAP connections. Simply put: If you're using POP, you may not be aware that there are potentially thousands of messages being put into an unchecked spam folder. If you decide to use POP, you can still view these messages using the webmail client for your service.
How IMAP works
IMAP is a method of connecting to our email server. It simply displays the contents of your mailbox as they appear on your server. Also, by default, spam folders are configured to be IMAP-Only, meaning you will need to use an IMAP connection in order to view and delete messages.
Many customers travel and want to securely check their email from various locations such as a wireless hotspot. For these customers, we offer the ability to use a SSL (Secure Sockets Layer) connection. This will allow any email client to connect to your NC Wireless address over an encrypted connection. We encourage all of our customers to use a secure connection when possible.
Email Port Numbers
We use the standard email ports for all of our services. Below is a list of these commonly used ports:
- POP, non-SSL: 110

Q: Do I need to purchase a SSL Certificate in order to make an SSL connection for email?
A: No, you can use the default SSL Certificate.

Email Setting Information
The Grid-Service imposes the following size limitations on outgoing email:
- Through local mail client: 25MB total, including message and attachment(s).
- Through webmail: 10MB total, including message and attachment(s); 2MB limit per attachment.
For example, you could compose a message in webmail with up to four 2MB attachments, if your email message itself is less than 2MB.
If you try to send an email that exceeds these limits, you may receive a message similar to the following:
- Server Response: '518.104.22.168 Message exceeds maximum fixed size (10485760)'
- Your message has size 137MB, which exceeds 25MB, the maximum allowed by the server.
Sending larger files
Consider using Dropbox or a commercial file sharing platform for sending larger files.
There are many great email applications that work with all of our services. Please use the provided settings to use your favorite thrid-party application. Support for third-party mail applications is outside our scope of support.
