ManageSieve Client Issues
=========================
Although this <ManageSieve.txt> server should comply with the draft
specification of the <ManageSieve.txt> protocol, quite a few clients don't.
This page lists the known client problems.
* *The TLS problem*:
* The core of the TLS problem is that a <ManageSieve.txt> server is required
to send an unsolicited CAPABILITY response right after successful TLS
negotiation. Older Cyrus servers did not do this and many clients
incorporated this protocol error as the standard, meaning that these do not
expect the CAPABILITY response and thus fail with subsequent commands.
However, now that Cyrus' Timsieved has changed its behaviour towards
protocol compliance, all those clients will follow eventually. The following
clients are known to have this TLS issue:
Thunderbird Sieve add-on:
TLS broken for old versions. Starting with version 0.1.5 the Thunderbird
Sieve add-on properly supports TLS.
KMail + kio_sieve:
TLS broken for old versions. This issue is fixed at least in kmail 1.9.9 /
kde 3.5.9.
SquirrelMail/AvelSieve:
For some users the !Avelsieve client stores scripts but fails to retrieve
them later. This problem is directly caused byAvelSieve's TLS support. A
quick way to fix this is not to enable TLS for <ManageSieve.txt>.
AvelSieve stable (v1.0.1) does not have TLS support at all, so you will
see this happen only with the development or SVN versions. Another issue
is that (at least with avelsieve-1.9.7) it is impossible to delete the
last rule of a script. For avelsieve-1.9.7 you find a patch that fixes
these two issues here
[http://www.rename-it.nl/dovecot/client-patches/avelsieve-1.9.7-dovecot.patch].
* *Smartsieve, Websieve*:
* These clients are specifically written for Cyrus timsieved and fail on
multiple stages of the protocol when connected to Dovecot <ManageSieve.txt>.
* /(Stephan Bosch)/: I intend to look at these in the future, but currently
these are very much unavailable for use with Dovecot. But, feel free to
fix these yourself:)
* /(Steffen "Stefreak" Neubauer)/: I've fixed the problems for smartsieve.
Just replace your lib/Managesieve.php with this
here:https://www.commail.org/sieve/lib/Managesieve.phps - HAVE FUN!
