Thallu - IMAP Server Details
The IMAP server (Internet the Message the Access Protocol) Protocol is a Application Layer for access to e-mail.
IMAP server is an alternative to POP with basic sending capabilities.The first version of the POP protocol had several shortcomings and the most serious of them was the lack of capacity to control the movement and storage of messages on the server. In POP, messages are downloaded from the mail server all at once after which they are deleted from the server, that is, there is no way to select messages to receive.
IMAP in 1986 implemented on DEC and no specification.IMAP2 implemented in 1987 then it described in 1988 in RFC 1064, finalized in 1990.IMAP3 1991 RFC 1203.IMAP2bis, the specification exists only in the draft version of 1993, plus RFC 2061 describes the differences between IMAP4 and IMAP2bis.IMAP4 1994 RFC 1730.IMAP4rev1 1996 RFC 2060, 2003 RFC 3501.
When using POP3, the client connects to the server only for the period of time necessary to download new messages. When using IMAP, the connection does not break while the user interface is active, and messages are downloaded only at the request of the client. This allows you to reduce the response time for users in whose mailboxes there are many messages of large volume.
The POP protocol requires the current client to be the only one connected to the mailbox. IMAP allows multiple clients to simultaneously access the mailbox and provides the client with the ability to track changes made by other clients connected at the same time.
Thanks to the flag system defined in IMAP4, the client can monitor the status of the message. flag data is saved on the server.
IMAP4 clients can create, rename, and delete mailboxes and move messages between mailboxes. In addition, you can use the IMAP4 Access Control List Extension to manage mailbox access rights.messages are searched on the server side.IMAP4 has an clear extension mechanism.
IMAP only works with messages and does not want any packages with special headers. Each message has several attributes associated with it. These IMAP's attributes can be defined individually or in conjunction with other attributes.
In IMAP, serial number of the message in the mailbox starts with 1. Each message starting from the second and has a serial number exactly 1 greater than the previous one.
This IMAP's attribute is a list of zero or more named tokens associated with this message. The flag is set by adding it to this list and zeroed by deleting it. There are two types of flags in IMAP 4.1. The flag may be permanent or valid only for the duration of this Session.
A system flag is a flag whose name is defined in the protocol specification. All system flags begin with a character.
The following system flags are currently defined in IMAP:
In IMAP, Time and date of receipt of the message. In the case of message delivery via SMTP and the date and time of delivery to the final recipient. For messages delivered by the copy command and the internal date and time of the sender of the message. When utilizing a command append then the date and time specified by the command parameters.
Other attributes in IMAP
An IMAP 4.1 connection involves establishing a connection between a client and a server. The client sends commands to the IMAP server and the server sends data and notifications about the status of the request to the server. All messages, both client and server, are in the form of lines ending with a special sequence.
An IMAP 4.1 server is in one of four states.Most commands can only be used in certain states.In a non-authenticated state, the client must provide a name and password before most commands are available to it. The transition to this state is made when a connection is established without preliminary authentication in IMAP.
LOGIN - Allows the client to use the user ID and password in plain text when registering with the IMAP server. This is not the best method, but sometimes this is the only way to connect to the server.
We can setup your own mailing server using Roundcube IMAP Email software. Also our service is Unlimited Bulk Mailing Server setup.Also You use IMAP read and replay in warmup process.
