The message body contains the actual information read by the receipt. If any information is received it informs the user about the mail.

When the user tries to read the mail it displays a list of mails with a short description of each mail in the mailbox. By selecting any of the mail user can view its contents on the terminal.

SMTP Protocol The SMTP model is of two type : End-to- end method Store-and- forward method The end to end model is used to communicate between different organizations whereas the store and forward method are used within an organization. Messages in a mailbox can be denoted in one of two ways: message sequence number or unique id. The message sequence number is the normal way. The messages in a mailbox are numbered from 1 to N where N is the number of messages in the mailbox.
There are never any gaps in the sequence numbers. If you tell imap to delete messages 3, 4, and 5 then it will return a value telling you that it has deleted messages 3, 3, and 3.
This is because when you deleted message 3, message 4 became the new message 3 just before it was deleted and then message 5 became message 3 just before it was deleted. A unique id of a message is a number associated with a message that is unique only within a mailbox. As long as the uidvalidity value of a mailbox doesn't change, the unique ids used in deleted messages will never be reused for new messages.
A flag is a symbol denoting that a message or mailbox has a certain property. We use keywords in Lisp to denote flags. There are two kinds of flags - System and User flags. System flags begin with the backslash character, which is an unfortunate design decision since that means that in Lisp we have to remember to use two backslashes e. A subset of the flags can be stored permanently in the mailbox with the messages.
When a connection is made to an imap server it will return the list of flags and permanent flags and these are stored in the mailbox server object returned for access by the program. Use the function make-imap-connection to connect to the imap server of a host machine. These functions work on mailboxes as a whole.

The mailbox argument to the functions is the object returned by make-imap-connection. If a return value isn't specified for a function then the return value isn't important - if something goes wrong an error will be signaled. The functions are select-mailbox , create-mailbox , delete-mailbox , and rename-mailbox.

The function mailbox-list returns information about a mailbox. The following functions work with the messages in the currently selected mailbox. The mailbox argument is the object returned by make-imap-connection. The messages argument is either a number denoting a single message , or is the list :seq N M denoting messages N through M , or is a list of numbers and :seq forms denoting the messages specified in the list. The mailbox object contains information about the imap server it's connected to as well as the currently selected mailbox.
This information can potentially be updated each time a request is made to the imap server. The following functions access values from the mailbox object. When using fetch-parts to access letters, you must specify the parts of the messages in which you are interested. There are a wide variety of specifiers, some redundant and overlapping, described in the imap specification in rfc We will describe the most common ones here. The specification is always a string. It may specify more than one thing by the use of parentheses in the string, e.
The result of a fetch-parts is a data structure containing all of the requested information.
https://suppmonigsu.ml The fetch-field function is then used to extract the particular information for the particular message. The imap server is able, using search-mailbox , to search for messages matching a search expression. A search-expression is a predicate described below , or one of these forms:. The value of mb is the mailbox object returned by make-imap-connection in Section 1.

There are seven messages at the moment. Fetch the whole 4th message. We could evaluate fetch-letter mb 4 here see fetch-letter instead and then not have to call fetch-field later. The value was returned inside a data structure designed to hold information about one or more messages. In order to extract the particular information we want we use fetch-field :. We use the search function to find all the messages containing the word blitzfig. It turns out there is only one. We then extract the contents of that message. We've been using message sequence numbers up to now.
