IMAP (Internet Message Access Protocol) handles email attachments by allowing them to be stored on the email server instead of being saved on the local device. This means that email attachments are not downloaded to the user’s device unless they choose to open or download them.
When an email with an attachment is received, the attachment is uploaded to the IMAP server along with the email message. The file size and type of the attachment are also recorded in the email metadata, which allows the user to view a list of attachments without having to download them.
Additionally, IMAP servers usually have a feature called “partial fetch” or “lazy fetch” which allows users to download only the parts of the email they need, including attachments. This reduces the amount of data that needs to be transferred and helps to save storage space on the user’s device.
Overall, IMAP provides a flexible and convenient way to handle email attachments, allowing users to manage and access their emails and attachments from multiple devices and locations.
