For this reason, email messages are generally left on the server until the user explicitly deletes them. <\/p>\n\n\n\n<p>An IMAP server typically listens on port number 143. IMAP over SSL\/TLS (IMAPS) usually happens on port number 993. STARTTLS is also supported by this protocol.<\/p>\n\n\n\n<p>This protocol was published in 1986 as a remote access mailbox protocol. IMAP2 was published in 1988 and updated in 1990. IMAP3 was published in 1991. IMAP2bis was published in 1993 which was renamed IMAP4.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Extensions<\/h2>\n\n\n\n<ul><li><strong>IDLE<\/strong>: This enables real-time notifications of the received emails.<\/li><li><strong>SORT<\/strong>: This sorts messages at the server so the email program can fetch certain ones without downloading all of them.<\/li><li><strong>THREAD<\/strong>: Allows email clients to retrieve related messages without downloading all mail in a folder.<\/li><li><strong>CHILDREN<\/strong>: This allows the implementation of a hierarchy of folders.<\/li><li><strong>Access Control List (ACL)<\/strong>: This specifies rights for individual users in each IMAP folder.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">IMAP Strengths<\/h2>\n\n\n\n<p>Typically, email messages are stored and organized in folders on an email server. The Email clients on end-users&#8217; computers and mobile devices replicate that structure and synchronize actions on these folders. <\/p>\n\n\n\n<p>These could be anything from deleting or moving messages between these folders. Each client connected to the same IMAP server will have the same synchronized view.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Disadvantages<\/h2>\n\n\n\n<p>IMAP is a more complex and difficult protocol to implement resulting in email clients and servers differing in how they interpret the standard.<\/p>\n\n\n\n<p>If you send a message through <a href=\"http:\/\/local.brightwhiz\/smtp-communication-protocol\/\">SMTP<\/a> from an IMAP connected client, it must be transmitted again through IMAP to be stored in the Sent folder of the IMAP account.<\/p>\n\n\n\n<p>All the synchronization going on may result in users finding email functionality slow and sometimes unreliable.<\/p>\n\n\n\n<p><strong>Related Reading:<\/strong><\/p>\n\n\n\n<ul><li>Follow this <a href=\"http:\/\/local.brightwhiz\/pop-internet-standard\/\">post to discover more about the POP Internet protocol<\/a> for email.<\/li><li>Check out this post <a href=\"http:\/\/local.brightwhiz\/comparing-pop-vs-imap-internet-standards\/\">comparing POP and IMAP<\/a>.<\/li><li>Find out <a href=\"http:\/\/local.brightwhiz\/smtp-communication-protocol\/\">more about SMTP communication protocol<\/a><\/li><\/ul>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve mail from a server over a TCP\/IP connection.
