dsync not replicating ".dovecot.sieve -> .sieve/managesieve.sieve"

[Tony]

Hi,

Currently using dovecot 2.3.2.1 and pigeonhole 0.5.2 on two identical 
hosts. I recently noticed ".dovecot.sieve" and 
".sieve/managesieve.sieve" are not replicating from one host to the 
other in either direction. Mail is having no trouble replicating on both 
hosts with dsync, it is only sieve files that are not replicating for 
unclear reasons.

# doveconf -n
host 1: https://ptpb.pw/njs3
host 2: https://ptpb.pw/KsfK

If I enable sieve debug logs I don't see anything that would cause 
alarm. The error logs are also not reporting any trouble. I have tested 
creating filters in Roundcube which is hosted from host1. This creates 
the sieve files as expected, but the same sieve files do not replicate 
to host2. When using Sieve with Thunderbird if the sieve files are 
created on host1 or host2, these are not replicating with dsync. So it 
does not seem to matter if the sieve files are created on either host 
and with any mail client, they just do not replicate at all.

I know at one point sieve files must have been replicating with dsync, 
it's just not clear to me at which version of dovecot and pigeonhole 
this began with the exception of mail files which are replicating.

Cheers,
Tony
