Solution, in my case, was to add

separator = /

to the inbox namespace as well. For some reason it didn't defaulted to whatever the mailbox format's internal separator was.

Subject: Problem with converting mdbox to MailDir

I have a problem to convert mdbox to MailDir. Log from that process looks like:

but when I will specify namespace to the inbox like

/bin/dsync -Dv -u user@domian.com mirror maildir:/tmp/destination/mailboxes/user@domian.com -n inbox

it throws different error:

doveadm(user@domian.com): Debug: Namespace : Using permissions from /var/mailboxes/64/b1/user@domian.com: mode=0700 gid=default

doveadm(user@domian.com): Fatal: execvp(maildir:/tmp/destination/mailboxes/user@domian.com) failed: No such file or directory

dsync-local(user@domian.com): Error: read(remote) failed: EOF (version not received

when /tmp/destination/mailboxes/user@domian.com directory exists

What I’m doing wrong in the process?
