dovecot - May 2020 - doveadm backup : Error: Failed to access mailbox

Hi All,

So close and yet so far.? ;-(
Have been migrating users from an old Dovecot server to a new one.
All of the users have doveadm backup'd perfectly, except for one !

What does the below mean ?

$ sudo doveadm -v -o imapc_user=jd at example.org.tld -o
imapc_password=secretSquirrel -o imapc_host=old-server.example.com backup -1 -R
-u jd at example.org.tld imapc:
dsync(jd at example.org.tld): Info: imapc(old-server.example.com:993): Connected
to 10.10.10.10:993 (local 10.10.10.11:35858)
dsync(jd at example.org.tld): Error: Failed to access mailbox Sent Messages
(jasmin at example: Mailbox doesn't exist: Sent Messages (jasmin at example
(0.001 + 0.000 secs).
dsync(jd at example.org.tld): Error: Failed to access mailbox Sent Messages
(jasmin at example.org: Mailbox doesn't exist: Sent Messages (jasmin at
example.org (0.001 + 0.000 secs).
dsync(jd at example.org.tld): Error: Failed to access mailbox Drafts (jasmin at
example: Mailbox doesn't exist: Drafts (jasmin at example (0.001 + 0.000
secs).
dsync(jd at example.org.tld): Error: Failed to access mailbox Drafts (jasmin at
example.org: Mailbox doesn't exist: Drafts (jasmin at example.org (0.001 +
0.000 secs).
dsync(jd at example.org.tld): Error: Failed to access mailbox Deleted Messages
(jasmin at example: Mailbox doesn't exist: Deleted Messages (jasmin at
example (0.001 + 0.000 secs).
dsync(jd at example.org.tld): Error: Failed to access mailbox Deleted Messages
(jasmin at example.org: Mailbox doesn't exist: Deleted Messages (jasmin at
example.org (0.001 + 0.000 secs).

FYI, found the solution.

It seems doveadm can't cope with brackets in mailbox names.

I moved the user's mails into non-braketed, deleted the bracketed and
doveadm backup worked fine after that.
