<![CDATA[Editing Sieve filters with Thunderbird's Sieve plugin doesn't seem to work reliably]]>I've successfully connected Thunderbird's Sieve mail-filter plug-in to my Cloudron mail account, and created a range of filters.

The problem is, most of these don't seem to work. I shelved this for a while, but I'm trying to work out why, again.

I recall seeing a post in which it was said that Thunderbird's sieve plugin doesn't work with Cloudron's sieve, but I can't find it again. Is that true, and if so, why is that?

I've tried installing Snappymail and the filters are visible in the UI there, they seem like they ought to work. But they don't.

I don't think the problem is because they're working but not selecting the email I think they should, but that is still a possibility. Is there any means for testing filters against Cloudron mail? Even hacky ones...

Thanks!
