Email client - Wikipedia. In Internet, an email client, email reader or more formally mail user agent (MUA) is a computer program in the category of groupware environments used to access and manage a user's email. Client is meant to be a role. For example, a web application which provides message management, composition, and reception functions may internally act as an email client; as a whole, it is commonly referred to as webmail. Likewise, email client may be referred to a piece of computer hardware or software whose primary or most visible role is to work as an email client. Retrieving messages from a mailbox. The most common arrangement is for an email user (the client) to make an arrangement with a remote Mail Transfer Agent (MTA) server for the receipt and storage of the client's emails. Klient And SalesmanThe MTA, using a suitable mail delivery agent (MDA), adds email messages to a client's storage as they arrive. The remote mail storage is referred to as the user's mailbox. The default setting on many Unix systems is for the mail server to store formatted messages in mbox, within the user's HOME directory. Of course, users of the system can log- in and run a mail client on the same computer that hosts their mailboxes; in which case, the server is not actually remote, other than in a generic sense. Klient Poczty AndroidEmails are stored in the user's mailbox on the remote server until the user's email client requests them to be downloaded to the user's computer, or can otherwise access the user's mailbox on the possibly remote server. The email client can be set up to connect to multiple mailboxes at the same time and to request the download of emails either automatically, such as at pre- set intervals, or the request can be manually initiated by the user. A user's mailbox can be accessed in two dedicated ways. The Post Office Protocol (POP) allows the user to download messages one at a time and only deletes them from the server after they have been successfully saved on local storage. It is possible to leave messages on the server to permit another client to access them. However, there is no provision for flagging a specific message as seen, answered, or forwarded, thus POP is not convenient for users who access the same mail from different machines.

Bitvise SSH Client Bitvise SSH Client is an SSH and SFTP client for Windows. It is developed and supported professionally by Bitvise. The SSH Client is robust, easy to install, easy to use, and supports all features supported by PuTTY, as well as the following. Alternatively, the Internet Message Access Protocol (IMAP) allows users to keep messages on the server, flagging them as appropriate. IMAP provides folders and sub- folders, which can be shared among different users with possibly different access rights. Typically, the Sent, Drafts, and Trash folders are created by default. IMAP features an idle extension for real time updates, providing faster notification than polling, where long lasting connections are feasible. See also the remote messages section below. In addition, the mailbox storage can be accessed directly by programs running on the server or via shared disks. Direct access can be more efficient but is less portable as it depends on the mailbox format; it is used by some email clients, including some webmail applications. Message composition. Some applications permit the use of a program- external editor. The email clients will perform formatting according to RFC 5. MIME for non- textual content and attachments. Headers include the destination fields, To, Cc, and Bcc, and the originator fields From which is the message's author(s), Sender in case there are more authors, and Reply- To in case responses should be addressed to a different mailbox. To better assist the user with destination fields, many clients maintain one or more address books and/or are able to connect to an LDAP directory server. For originator fields, clients may support different identities. Client settings require the user's real name and email address for each user's identity, and possibly a list of LDAP servers. Submitting messages to a server. The email client is usually set up automatically to connect to the user's mail server, which is typically either an MSA or an MTA, two variations of the SMTP protocol. The email client which uses the SMTP protocol creates an authentication extension, which the mail server uses to authenticate the sender. This method eases modularity and nomadic computing. The older method was for the mail server to recognize the client's IP address, e. There is a non- standard port 4. SSL encrypted SMTP sessions, that many clients and servers support for backward compatibility. Encryption. Email encryption enables privacy to be safeguarded by encrypting the mail sessions, the body of the message, or both. Without it, anyone with network access and the right tools can monitor email and obtain login passwords. Examples of concern include the government censorship and surveillance and fellow wireless network users such as at an Internet cafe. All relevant email protocols have an option to encrypt the whole session, to prevent a user's name and password from being sniffed. They are strongly suggested for nomadic users and whenever the Internet access provider is not trusted. At any further hop, messages may be transmitted with or without encryption, depending solely on the general configuration of the transmitting server and the capabilities of the receiving one. Encrypted mail sessions deliver messages in their original format, i. The latter server is operated by an email hosting service provider, possibly a different entity than the Internet access provider currently at hand. Encryption of the message body. S/MIME employs a model based on a trusted certificate authority (CA) that signs users' public keys. Open. PGP employs a somewhat more flexible web of trust mechanism that allows users to sign one another's public keys. Open. PGP is also more flexible in the format of the messages, in that it still supports plain message encryption and signing as they used to work before MIME standardization. In both cases, only the message body is encrypted. Header fields, including originator, recipients, and subject, remain in plain text. Webmail. Webmail has several advantages, including an ability to send and receive email away from the user's normal base using a web browser, thus eliminating the need to install an email client on the user's device. Some websites are dedicated to providing email services, and many Internet service providers provide webmail services as part of their Internet service package. The main limitations of webmail are that user interactions are subject to the website's operating system and the general inability to download email messages and compose or work on the messages offline, although there are software packages that can integrate parts of the webmail functionality into the OS (e. By contrast, both IMAP and webmail keep messages on the server as their method of operating, albeit users can make local copies as they like. Keeping messages on the server has advantages and disadvantages. Attachments are files that are not part of the email proper, but are sent with the email. Most email clients use a User- Agent. According to RFC 2. RFC 6. 40. 9, Message Submission for Mail, details the role of the Mail submission agent. RFC 5. 06. 8, Email Submission Operations: Access and Accountability Requirements, provides a survey of the concepts of MTA, MSA, MDA, and MUA. For MSA, IMAP and POP3, the table reports also the labels that a client can use to query the SRV records and discover both the host name and the port number of the corresponding service. RFC 2. 59. 5 discourages the use of the previously established ports 9. POP, IMAP and SMTP while using TLS when available. Proprietary client protocols.
