What is IMAP and POP3?
IMAP and POP3 are internet standard protocols for email, allowing your email program to access email accounts on your web space.
IMAP allows multiple clients to access the same mailbox, while keeping the email messages available on the server for later access via webmail.
POP3 downloads the messages, while removing the messages from the server. The emails are then no longer accessible via webmail or a mail program.
We recommend that you use IMAP when setting up your email program.
