With MegabytesOne you have both POP and IMAP email. Understanding the difference will help you decide which option is best for you. The choice between POP and IMAP only applies to the configuration of your computer, there are no administrative changes or options to choose between the two.
POP mail is downloaded to your computer when you check your mail. The mail client (i.e. Thunderbird) will download the messages from the mail server and store them on your computer.
Features of POP Mail
IMAP mail acts the same way, but messages are never downloaded to your computer, they are instead kept on the mail server and accessed via your mail client. This allows you to access your mail from any computer at any time using WebMail. It also requires that your mailbox never exceed the space limitation imposed by the administrator, so you must remember to delete messages – especially those with large attachments – when you are finished with them.
IMAP is also useful if you use more than one computer and would like to configure more than one email client to check your email. Using IMAP, you'll have access to all of your mail from any number of computers without having to set additional options or worry about what mail you've already read.
Features of IMAP Mail
