Have you tried with the latest nightly build?

Hello, I have upgraded to the last nightly build 2017_12_07, but the filters still do not work properly.

Can you share the generated Sieve script? Have you change SOGoSieveFolderEncoding?

I am experiencing the same issue on the SoGo webmail of Gandi.

Any simple rule does not work when the rule has to place the message in a sub-folder of inbox.
The same rule works perfectly when the destination folder is at the same level of the inbox folder.

I was wondering if the way the sub-folders were created could play a role. I created the sub-folders directly in my email client (Thunderbird) for example.

I'll be glad to add any information that can be useful. However I am only a user of Gandi service so I have no access to any config file. They are aware of the problem, and answered that on their side it works...

Hello, we've set this up:

/lib64/GNUstep/Frameworks/SOGo.framework/Versions/3/Resources/SOGoDefaults.plist: SOGoSieveFolderEncoding = "UTF-7";

we did not make any changes to the settings

Create a new filter using a recent nightly build and show us the generated Sieve script.
