Hi,

I've set up 2 servers with dovecot 2.2.9 using maildir using structure: /var/maildir/domain/localpart Server A: mx1.xxx.de Server B: mx2.xxx.de

Mails are delivered to dovecot only on server A by exim4/dovecot deliver

replication to Server B works immediatelly: mark mail as read on server A, mail is marked as read on server B.

BUT: when i mark a mail as read on Server B, noting happens. On Server A I get messages like this in dovecot-error.log:

2014-10-22 22:35:05 dsync-server(localpart@domain.de): Error: stat(/var/maildir/domain.de/localpart/.dovecot-sync.lock/tmp) failed: Not a directory 2014-10-22 22:35:05 dsync-server(localpart@domain.de): Error: Failed to access mailbox dovecot-sync.lock: Internal error occurred. Refer to server log for more information. [2014-10-22 22:35:05]

I googled a bit, this could habben if there is a file ".dovecot-sync.lock" in the maildir, but I've double checked that, there is no such file... Why does it work in one direction, but not in the other?

Please help

best regards Felix
