DESCRIPTION
sieve-connect is a client for the "MANAGESIEVE" protocol, which is an RFC-specified protocol for
manipulation of "Sieve" scripts in a repository. More simply, sieve-connect lets you control your mail-
filtering rule files on a mail server.
sieve-connect can be invoked with an action from the command-line to make it easy to script one-shot
actions, it can be provided with a script file or it can be left to enter an interactive command-loop,
where it supports tab-completion (if the supporting Perl module is available) and basic navigation of the
local file-system in the style of "FTP" clients.
sieve-connect supports the use of "TLS" via the "STARTTLS" command, including authentication via client
certificates. "sieve-connect" also supports whichever "SASL" mechanisms your Authen::SASL::Perl library
provides, as long as they do not require SASL protection layers.
In Interactive mode, a "help" command is available. Command parameters with a "%" in them are examined
to see if they match %KEYWORD, where "KEYWORD" is always in upper-case. The list of keywords may be
retrieved with the "keywords" command and includes items such as %DATE, %USER, etc.
OPTIONS
The remote sieve script name defaults to the same as the local sieve script name, so just specify the
local one if only one is needed; it was a deliberate decision to have the defaults this way around, to
make people think about names in the local filesystem. There is no default script name.
The --debug option turns on diagnostic traces. The --debugsasl option asks the SASL library for
debugging. The --dumptlsinfo shows the TLS (SSL) peer information; if specified together with --debug
then the server's PEM certificate will be provided as debug trace.
The --version option shows version information. When combined with --debug it will show implementation
dependency versions.
The server can be a host or IP address, IPv4 or IPv6; the default is $IMAP_SERVER from the environment
(if it's not a unix-domain socket path) with any port specificaion stripped off, else localhost. The
port can be any Perl port specification, default is sieve(4190). The --4 or --6 options may be used to
coerce IPv4 or IPv6.
By default, the server is taken to be a domain, for which SRV records are looked up; use --nosrv to
inhibit SRV record lookup.
The --user option will be required unless you're on a Unix system with getpwuid() available and your
Cyrus account name matches your system account name. --authmech can be used to force a particular
authentication mechanism. --authzid can be used to request authorisation to act as the specified id.
--realm can be used to try to pass realm information to the authentication mechanism. If you want to
provide a password programmatically, use --passwordfd to state which file descriptor (typically 0) the
password can be read from. Everything until the newline before EOF is the password, so it can contain
embedded newlines. Do not provide passwords on a command-line or in a process environment.
If you are willing to accept the risk of man-in-the-middle active attacks and you are unable to arrange
for the relevant Certificate Authority certificate to be available, then you can lower your safety with
the --notlsverify option, also spelt --nosslverify.
For SSL client certificate authentication, either --clientkeycert may be used to refer to a file with
both the key and cert present or both --clientkey and --clientcert should point to the relevant files.
The data should be in PEM file-format.
The --noclearauth option will prevent use of cleartext authentication mechanisms unless protected by TLS.
The --noclearchan option will mandate use of some confidentiality layer; at this time only TLS is
supported.
By default, the server's "VERSION" capability will be used to filter the commands available. Use
--ignoreserverversion to prevent this.
The remaining options denote actions. One, and only one, action may be present. If no action is
present, the interactive mode is entered. If the exec action is present, commands are read from the
script instead.
It is believed that the names of the actions are sufficiently self-descriptive for any English-speaker
who can safely be allowed unaccompanied computer usage.
(If --server is not explicitly stated, it may be provided at the end of the command-line for
compatibility with sieveshell.)
ENVIRONMENT
$IMAP_SERVER for a default IMAP server. $USERNAME and $LOGNAME where the "getpwuid()" function is not
available.
BUGS
If the authentication protocol negotiates a protection layer then things will rapidly Go Bad. A
mitigating factor is that no protection layer should be negotiated whilst under STARTTLS protection.
Just use TLS!
When listing scripts, the format is based upon the raw server output, assuming that the server uses
quoted-strings for the script names. The output is just passed back on the basis that it's a fairly good
interface to pass to a program. But a server could choose to use literal strings, even though the
results are defined as line-break separated -- that would mean that some linebreaks are special.
Hopefully no server will do this.
If sieve-connect fails to connect to an IPv4 server without the -4 option being explicitly passed, then
you've encountered a portability issue in the IO::Socket::INET6 Perl library and need to upgrade that.
Most historical implementations used port 2000 for ManageSieve. RFC5804 allocates port 4190. This tool
uses a port-spec of "sieve(4190)" as the default port, which means that an /etc/services (or substitute)
entry for "sieve" as a TCP service takes precedence, but if that is not present, to assume 4190 as the
default. This change means that if you're still using port 2000 and do not have an /etc/services entry,
updating to/beyond release 0.75 of this tool will break invocations which do not specify a port. The
specification of the default port was moved to the user-configurable section at the top of the script and
administrators may wish to override the shipped default. You can bypass all of this mess by publishing
SRV records, per RFC5804.
The Net::DNS Perl module does not (at time of writing) provide full support for weighted prioritised SRV
records and I have not made any effort to fix this; whatever the default sort algorithm provides for SRV
is what is used for ordering.
Probably need to sit down and work through the final RFC and see if any functionality is still missing.
NON-BUGS
Actually uses STARTTLS. Can handle script names with embedded whitespace. Author needs access to a
server which handles embedded quote characters properly to complete testing of that.
HISTORY
sieve-connect was written as a demonstration for the "info-cyrus" mailing-list, 2006-11-14. It was a
single-action-and-quit script for scripting purposes. The command-loop code was written (two days) later
and deliberately designed to be compatible with sieveshell.

PREREQUISITES
Perl. Authen::SASL. IO::Socket::INET6. IO::Socket::SSL (at least version 0.97). Pod::Usage. Net::DNS
for SRV lookup. Pod::Simple::Text for built-in man command (optional). Term::ReadKey to get passwords
without echo. Various other Perl modules which are believed to be standard. Term::ReadLine will
significantly improve interactive mode. Term::ReadLine::Gnu will improve it further by allowing tab-
completion.
INTEROPERABILITY
sieve-connect is regularly tested with the timsieved server distributed with the Cyrus IMAP server.
Further interoperability testing is underway, more is desired (test accounts appreciated!).
