POP3 or IMAP or Webmail for Email?
When you host your web site with us that also means we are going to handle your email accounts as well. So when you have have an email address we need to make sure that you receive those emails properly. As with everything else there with email you have many options.
The first option is called POP3. POP3 standard for Post Office Protocol version three. Using the POP3 method you would use a email client on your computer such as Microsoft Outlook or Eudora. When you check your mail the client will contact the server and download all of the messages from the server to your client. In most configurations the client will delete the email on the server once it is delivered to your computer.
Many people like this option because you have full control of your email. You can easily change your service provider because all of your mail is stored on your own computer. Additionally you have much less restrictions on your mail. Many providers limit the size of the emails you can keep and/or the time you can keep them. With POP3 though once the email has been retrieved down to your own computer system it doesn't take up any space on the server itself.
One of the concerns though is since the email is stored only on your computer you must make sure that it is being backed up properly. If something were to happen to your computer then all of your email would be lost forever.
Since POP3 will remove the email from the server if you were to check your email using the webmail interface then you would not see the emails that have already been downloaded to the client. This applies to other devices that access your email too such as all of the smart phones out there.
IMAP or Internet Message Access Protocol is another method that an email client can connect to the server and check your email. IMAP though keeps the email stored on the server instead of downloading it to your computer. IMAP is great for people who need to be able to check their email from multiple devices, or use multiple computers. However you do need to have a consistent connection to the Internet so this is not a good solution if you have only a dial-up connection.
Since IMAP stores email on the server you will run into problems if you try to keep all of your emails online. There are workarounds though depending on your situation. For example if you have a desktop computer you can use client software that allows you to move emails off of the IMAP connection and into your folder structure on your own system. This would enabled you to keep your incoming email on your smart phone, while allowing you to archive gigabytes of email at the same time, being the best of both worlds.
The last option is webmail. Webmail is the option where you do not even use any type of client software. There is nothing to install on your computer. All you do is go to the correct web site location and enter your user name and password. This is a great option if you use public computers such as at a library or school, where you can't really download and install software. Webmail use to be very basic, but today they have many features and some people even prefer them over using the client based software.
