What is supported

Currently, the provided parser supports most of the functionalities described in the RFC. The only exception concerns section 2.4.2.4. Encoding Characters Using “encoded-character” which is not supported.

The following extensions are also supported:

• Copying Without Side Effects (RFC 3894)

• Body (RFC 5173)

• Vacation (RFC 5230)

• Seconds parameter for Vacation (RFC 6131)

• Relational (RFC 5231)

• Imap4flags (RFC 5232)

• Regular expression (Draft)

• Notifications (RFC 5435)

• Environment (RFC 5183)

The following extensions are partially supported:

• Date and Index (RFC 5260)

• Checking Mailbox Status and Accessing Mailbox Metadata (RFC 5490)

Extending the parser

It is possible to extend the parser by adding new supported commands. For example:

import sievelib

class MyCommand(sievelib.commands.ActionCommand):
    args_definition = [
        {"name": "testtag",
            "type": ["tag"],
            "values": [":testtag"],
            "extra_arg": {"type": "number",
                          "required": False},
            "required": False},
        {"name": "recipients",
            "type": ["string", "stringlist"],
            "required": True}
    ]

sievelib.commands.add_commands(MyCommand)

Basic usage

The parser can either be used from the command-line:

$ cd sievelib
$ python parser.py test.sieve
Syntax OK
$

Or can be used from a python environment (or script/module):

>>> from sievelib.parser import Parser
>>> p = Parser()
>>> p.parse('require ["fileinto"];')
True
>>> p.dump()
require (type: control)
    ["fileinto"]
>>>
>>> p.parse('require ["fileinto"]')
False
>>> p.error
'line 1: parsing error: end of script reached while semicolon expected'
>>>

Simple filters creation

Some high-level classes are provided with the factory module, they make the generation of Sieve rules easier:

>>> from sievelib.factory import FiltersSet
>>> fs = FiltersSet("test")
>>> fs.addfilter("rule1",
...              [("Sender", ":is", "[e-mail]"),],
...              [("fileinto", "Toto"),])
>>> fs.tosieve()
require ["fileinto"];

# Filter: rule1
if anyof (header :is "Sender" "[e-mail]") {
    fileinto "Toto";
}
>>>

Additional documentation is available within source code.

ManageSieve tools

What is supported

All mandatory commands are supported. The RENAME extension is supported, with a simulated behaviour for server that do not support it.

For the AUTHENTICATE command, supported mechanisms are DIGEST-MD5, PLAIN, LOGIN, OAUTHBEARER and XOAUTH2.

Both explicit TLS via STARTTLS and implicit TLS are supported.

Basic usage

The ManageSieve client is intended to be used from another python application (there isn’t any shell provided):

>>> from sievelib.managesieve import Client
>>> c = Client("server.example.com")
>>> c.connect("user", "password", starttls=False, authmech="DIGEST-MD5")
True
>>> c.listscripts()
("active_script", ["script1", "script2"])
>>> c.setactive("script1")
True
>>> c.havespace("script3", 45)
True
>>>
