IMAP (the latest version is IMAP4) is a client/server protocol in which e-mail is received and held for you by your Internet server. References LabSim for Security Pro, Section 6.2. 80. To put it simply, a port number is the means through which a specific message is identified when it’s forwarded to a server. [7][8] Although some of its commands and responses were similar to IMAP2, the interim protocol lacked command/response tagging and thus its syntax was incompatible with all other versions of IMAP. IMAP3 is an extremely rare variant of IMAP. Each port number identifies a distinct service, and each host can have 65535 ports per IP address. 21. An alternative protocol is Internet Message Access Protocol . However, push IMAP has not been generally accepted and current IETF work has addressed the problem in other ways (see the Lemonade Profile for more information).

The following tables give you the facts on IP protocols, ports, and address ranges. The second service is usually either the Post Office Protocol (POP) or the Internet Message Access Protocol (IMAP) which is used by e-mail client applications on users' personal computers to fetch email messages from the server. ICMP is part of the Internet protocol suite as defined in RFC 792.ICMP messages are typically used for diagnostic or control purposes or generated in response to errors in IP operations (as specified in RFC 1122).ICMP errors are directed to the source IP address of the originating packet. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Clients may store local copies of the messages, but these are considered to be a temporary cache. Multiple mailbox support also allows servers to provide access to shared and public folders. Email Clients such as Microsoft Outlook, Netscape, Eudora, and many others, using imap protocol to retrieve their eMail, connect to port 143 of a remote eMail server. Technical details.

IMAP4 runs on top of the Microsoft Internet Information Service (IIS) Admin Service and enables client access to the Exchange Information Store. IMAP over SSL/TLS (IMAPS) is assigned the port number 993.[2][3]. These ports are assigned to specific server sevice by the Internet Assigned Numbers Authority (IANA). This is an example IMAP connection as taken from RFC 3501 section 8: Application layer internet protocol for e-mail retrieval and storage, "IMAP" redirects here. Unless the mail storage and searching algorithms on the server are carefully implemented, a client can potentially consume large amounts of server resources when searching massive mailboxes. Abstract The Internet Message Access Protocol, Version 4rev1 (IMAP4rev1) allows a client to access and manipulate electronic mail messages on a server. Port Number. The current version is defined by RFC 3501. Dynamic Host Configuration Protocol. Virtually all modern e-mail clients and servers support IMAP, which along with the earlier POP3 (Post Office Protocol) are the two most prevalent standard protocols for email retrieval. The interim protocol was quickly replaced by the Interactive Mail Access Protocol (IMAP2), defined in RFC 1064 (in 1988) and later updated by RFC 1176 (in 1990). The POP service listens on TCP port number 110. However, the specification also allows these UIDs to be invalidated with no restrictions, practically defeating their purpose.[17]. In addition to this, Courier Mail Server offers a non-standard method of sending using IMAP by copying an outgoing message to a dedicated outbox folder. A POP3 server listens on well-known port number 110 for service requests. [9] It was published as RFC 1203 in 1991. Both protocols are supported by all modern email clients and web servers. The port number identifies what type of port it is. Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. Description. IMAP (Internet Message Access Protocol), as opposed to POP3, is a two-way incoming mail protocol that only downloads email headers instead of its entire content. All the new generation or web-based email services like Gmail, Outlook and Yahoo Mail supports IMAP service. Alternatively, STARTTLS can be used to provide secure communications between the MUA communicating with the MSA or MTA implementing the SMTP Protocol. On the other hand, if you use POP3, your messages are stored on your local computer, which reduces the space your email account uses on your web server. UDP/TCP 137 NetBIOS Name Service. This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite … File Transfer Protocol (FTP) (RFC 959) TCP.

Learn everything about email protocols and their port numbers. SMTP over SSL/TLS port number: 465 For example, port 80 is used by web servers. IMAP4 clients need to maintain a TCP/IP connection to the IMAP server in order to be notified of the arrival of new mail. The most common ports are: FTP (21): FTP or File Transfer Protocol is used to transfer files across the Internet. The IMAP4 Access Control List (ACL) Extension (RFC 4314) may be used to regulate access rights. Unlike some proprietary protocols which combine sending and retrieval operations, sending a message and saving a copy in a server-side folder with a base-level IMAP client requires transmitting the message content twice, once to SMTP for delivery and a second time to IMAP to store in a sent mail folder. File Transfer Protocol (FTP) Data Transfer.

The POP protocol requires the currently connected client to be the only client connected to the mailbox. IMAP can be thought of as a remote file server. IMAP4rev1 also provides the capability for an offline client to resynchronize with the server. Assigned Internet Protocol Numbers Registration Procedure(s) IESG Approval or Standards Action Reference Note In the Internet Protocol version 4 (IPv4) there is a field called "Protocol" to identify the next level protocol. SNMP. By contrast, the Internet Message Access Protocol (IMAP) was designed to normally leave all messages on the server to permit management with multiple client applications, and to support both connected (online) and disconnected (offline) modes of operation. Port Number. This mechanism avoids requiring clients to download every message in the mailbox in order to perform these searches. These flags are stored on the server, so different clients accessing the same mailbox at different times can detect state changes made by other clients. When using POP, clients typically connect to the e-mail server briefly, only as long as it takes to download new messages. [15] The IMAP2bis.TXT draft documented the state of extensions to IMAP2 as of December 1992. Common Protocol Numbers . [10] IMAP3 was never accepted by the marketplace.
