Domain Email Settings - IMAP and POP mail protocol comparison

Introduction to email

NWD, LLC hosting includes mail service with its plans allowing hosting clients to send and receive email using their domain name. The default and supported method to access email is by using NWD, LLC RoundMail Webmail application.  Learn more about Webmail.

NWD, LLC mail service is always ready to accept messages using an email client such as Microsoft Outlook or Apple Mail (or any other standard email client).

POP and IMAP are the two most common email protocols on the internet. They both allow an email client to communicate with the mail servers, but they do so in very different ways.

 

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 and if so, should be configured to only do so for several days, not eternity.  Following are some features of POP. 

  • Access: Because your email is stored on your computer, you must be at your computer to access your email.

  • Storage: You don’t need to worry about running out of online storage space. Because emails are downloaded to your computer, you can keep as many emails as your computer can store.

  • Backup: You should implement an effective backup system for your computer, in case you need to retrieve lost or deleted emails.

  • Internet connection: You must have an Internet connection to download your email, but you can view your downloaded email offline (that is, without an Internet connection).

 

How IMAP works

IMAP is the preferred method of connecting to your email server. It simply displays the contents of your mailbox as they appear on your server. Following are some features of IMAP.

  • Access: Because emails are stored on the email server, you can access and manage your email and email folders from multiple computers or mobile devices.

  • Storage: If you have limited online storage space, you might need to delete some emails periodically to avoid exceeding your storage capacity.

  • Backup: Email is automatically backed up every evening. If you accidentally delete an email, your email administrator can retrieve it, even up to 14 days later.

  • Internet connection: You must have an Internet connection to access your email.


Please Note: With this method be careful of over loading your server-side mailbox and archive your messages regularly on your LOCAL computer.  We are not responsible for missing messages if your mailbox becomes corrupt because it is too large.  Ultimately you need to save a copy of your messages on your local computer to best ensure you have a copy of important messages. NWD, LLC Mail services is to be used for communication, not for long term storage of documents or the like.

Email Security

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 NWD, LLC mail services over an encrypted connection. We encourage all of our customers to use a secure connection when possible.
