The virtual emails do not contain the full MIME attachment data but instead include some or all header fields of the parent email which contains the MIME attachment and a link to the MIME part of the MIME attachment in this email. The virtual emails may be stored in a separate namespace, or a folder which may be hidden from some IMAP clients, on an IMAP server. The virtual emails may be indexed by the IMAP server like any other email. Virtual emails may be created when new emails arrive on the IMAP server and synchronized automatically, e.g., when the parent email changes. As such, standard IMAP commands like FETCH, SEARCH, SORT, THREAD, etc. may be used for virtual emails."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Virtual emails for IMAP commands","description":"Some embodiments provide a method to extract metadata of MIME attachments or other distinguishable MIME parts of MIME emails into virtual emails.
