Replication fails with dsync-server(admin at asergis.com): Error: Couldn't create lock /home/admin/.dovecot-sync.lock: No such file or directory

[Vladimir Tiukhtin]

Hello


I have configured replication using dsync. It fails with a message

Error: Couldn't create lock /home/admin/.dovecot-sync.lock: No such file 
or directory

This directory predictably does not exist - all my users are supposed to 
be virtual.  I can not find an option to switch this off. At the same 
time if I try manual replication I get segfault error
