dovecot - Jul 2019 - doveadm migration to server with no root access

Hi

I am trying to do mailbox migrations using doveadm to a server that I do not
have root access on without success. Is this possible?

What I have done and results:

ssh to server with mailboxes to copy and then su
cp /etc/dovecot/dovecot.conf  /root/tmp/dovecot_new.conf
append text below** to end of dovecot_new.conf
try to copy mail 3 different ways (all fail see error messages)

doveadm -D -v -c /root/tmp/dovecot_new.conf -o mail_fsync=never sync -1 -u
test at propertyzone.co.za pop3c:
fail with: Error: Mailbox INBOX.Archive sync: mailbox_set_subscribed failed:
Subscriptions not supported

doveadm -D -v -c /root/tmp/dovecot_new.conf -o mail_fsync=never sync -u
test at propertyzone.co.za pop3c:
fail with: Error: Can't create mailbox INBOX.Archive: POP3 mailbox creation
isn't supported

doveadm -D -v -c /root/tmp/dovecot_new.conf -o mail_fsync=never backup -u
test at propertyzone.co.za pop3c:
fail with: dsync(test at propertyzone.co.za): Panic: file
mailbox-list-delete.c: line 473 (mailbox_list_delete_symlink_default):
assertion failed: (ret > 0)


** append at end of dovecot_new.conf
pop3c_host = dedi225.jnb3.host-h.net
pop3c_user = test at propertyzone.co.za
pop3c_password = *****
namespace inbox {
  inbox = yes
}
namespace {
  prefix = POP3-MIGRATION-NS/
  location = pop3c:
  list = no
  hidden = yes
}
protocol doveadm {
  mail_plugins = $mail_plugins pop3_migration
}
plugin {
  pop3_migration_mailbox = POP3-MIGRATION-NS/INBOX

Hi,

you can't migrate by pushing to imapc: or pop3c: host. It's not
supported and in fact is not even possible without losing data.

you need to pull the mails by running doveadm on the new server.

Hi Sami

Thanks for your response.

Is it then possible to run doveadm without root permission? I've tried, but
get the following errors (using the same kind of setup as my initial post).

command:
doveadm -D -v -c /root/tmp/dovecot_hetz.conf -o mail_fsync=never backup -u
test at propertyzone.co.za pop3c:
response:
doveadm(test at propertyzone.co.za): Error: userdb lookup:
connect(/var/run/dovecot/auth-userdb) failed: Permission denied
(euid=1264(propenmnvk) egid=1264(propenmnvk) missing +r perm:
/var/run/dovecot/auth-userdb, we're not in group 8(mail), dir owned by 0:0
mode=0755)
doveadm(test at propertyzone.co.za): Error: User lookup failed: Internal error
occurred. Refer to server log for more information.
