What is IMAP?
IMAP, or Internet Message Access Protocol, is an email retrieval protocol that allows users to access and manage their email messages directly on the mail server, keeping messages synchronized across multiple devices.
How Does Imap Work?
IMAP works by maintaining a persistent connection between the email client and the mail server, allowing users to read, organize, and manage emails without downloading them to a single device. When you read, delete, or move a message on one device, those changes are reflected on all other devices accessing the same account. This makes IMAP the preferred protocol for users who access their email from multiple computers, phones, and tablets.
Unlike POP3, which downloads messages to a local device and typically removes them from the server, IMAP stores messages on the server by default. This means IMAP accounts require sufficient server storage space, which is usually included in hosting plans with email services. IMAP uses port 143 for standard connections and port 993 for secure connections encrypted with SSL or TLS, and most modern email clients and hosting providers support IMAP by default.
