class IMAP4:
|

|
|
||
|
r"""IMAP4 client class.
|
||
|
|
||
|
Instantiate with: IMAP4([host[, port]])
|
||
|
|
||
|
host - host's name (default: localhost);
|
||
|
port - port number (default: standard IMAP4 port).
|
||
|
|
||
|
All IMAP4rev1 commands are supported by methods of the same
|
||
|
name (in lower-case).
|
||
|
|
||
|
All arguments to commands are converted to strings, except for
|
||
|
AUTHENTICATE, and the last argument to APPEND which is passed as
|
||
|
an IMAP4 literal. If necessary (the string contains any
|
||
|
non-printing characters or white-space and isn't enclosed with
|
||
|
either parentheses or double quotes) each string is quoted.
|
||
|
However, the 'password' argument to the LOGIN command is always
|
||
|
quoted. If you want to avoid having an argument string quoted
|
||
|
(eg: the 'flags' argument to STORE) then enclose the string in
|
||
|
parentheses (eg: "(\Deleted)").
|
||
|
|
||
|
Each command returns a tuple: (type, [data, ...]) where 'type'
|
||
|
is usually 'OK' or 'NO', and 'data' is either the text from the
|
||
|
tagged response, or untagged results from command. Each 'data'
|
||
|
is either a string, or a tuple. If a tuple, then the first part
|
||
|
is the header of the response, and the second part contains
|
||
|
the data (ie: 'literal' value).
|
||
|
|
||
|
Errors raise the exception class <instance>.error("<reason>").
|
||
|
IMAP4 server errors raise <instance>.abort("<reason>"),
|
||
|
which is a sub-class of 'error'. Mailbox status changes
|
||
|
from READ-WRITE to READ-ONLY raise the exception class
|
||
|
<instance>.readonly("<reason>"), which is a sub-class of 'abort'.
|
||
|
|
||
|
"error" exceptions imply a program error.
|
||
|
"abort" exceptions imply the connection should be reset, and
|
||
|
the command re-tried.
|
||
|
"readonly" exceptions imply the command should be re-tried.
|
||
|
|
||
|
Note: to use this module, you must read the RFCs pertaining to the
|
||
|
IMAP4 protocol, as the semantics of the arguments to each IMAP4
|
||
|
command are left to the invoker, not to mention the results. Also,
|
||
|
most IMAP servers implement a sub-set of the commands available here.
