Are you using the latest nightly build of the sieve addon? All "stable" releases are outdated.

Regards, Thomas Herrmann

you need the updated beta sieve plugin 0.2.3d https://github.com/thsmi/sieve/blob/master/nightly/0.2.3/sieve-0.2.3d.xpi

see https://github.com/thsmi/sieve/issues/26 for the reason why it is not available via mozilla plugins site

this should fix the problem in thunderbird. (I use it myself having had the same issue) Regards, Tim

I'm not sure when this problem first occurred - it is many months since I last editted a sieve filter. I am certainly several versions of Thunderbird and, probably, a few versions of Dovecot on from when I last editted a sieve filter. However, I do know that I have done so in the past.

I have just built Dovecot 2.2.13 and Pigeonhole 0.4.3, installed and running on Slackware 14.1 x64.

I am running an up-to-date version of Thunderbird (31.0) on Arch Linux x64.

The sieve filters are definitely being applied to incoming mail, and working perfectly well.

However, when I attempt to edit the Sieve Filters (from Thunderbird Tools->Sieve Message Filters...), the Sieve Filters tab is displayed, but not populated (eg, the Server Sieve Capabilities are not displayed, and there is an endless 'hourglass' displayed in the main mailfilters pane.

Does anyone recognise the symptoms and can advise how to resolve the problem, or suggest what logs I should examine/post in order to identify the cause?
