| 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. |
