>> This was an lmtpd bug in earlier versions of 3.0.  It was fixed in  
>> 3.0.6, and this was noted in the release notes:
>>
>> https://www.cyrusimap.org/imap/download/release-notes/3.0/x/3.0.6.html:
>>> Fixed Issue #2303: lmtpd(8) now looks for sieve scripts in the  
>>> same directories as the rest of cyrus (including timsieved(8)).
>>> Please note that if you had manually installed sieve scripts to  
>>> the directories lmtpd used to look in, these will need to be moved.
>> It sounds like your setup was taking the bug into account (using  
>> the '^' paths that lmtpd expected), and since lmtpd has been fixed  
>> to use dots, you're now seeing the reverse of the problem.

> I don't think #2303 is related to our problem. Issue #2303 was a

> LMTP and the rest of Cyrus between 3.0.0-beta2 and 3.0.6. We've  
> upgraded directly from 2.5.7 to
> 3.0.6. Also, in our case subscription file names are affected too.

> significant incompatible change that should be documented in 3.0  
> Upgrade Guide. I'm also afraid if
> there're no more similar "silent" changes that we didn't find yet.

Just to make sure, you have seen


> Important config options: unixhierarchysep: and altnamespace:  
> defaults have changed in imapd.conf(5). Implications are outlined in

> Namespace. Please also see “Sieve Scripts,” below.

>    unixhierarchysep: on
>    altnamespace: on
