Mailcow-dockerized: doveadm import over ssh

[cklabautermann]

First of all I´d like to thank for the great work! I would love to import my actual dovecot via doveadm into mailcow. unfortunately I´m no docker guru and it seems to me that the dovecot container misses ssh, so I can´t import the mail accounts from the remote server.

Can you give me a hint how to achieve this?

what I have tried until now:
docker-compose exec dovecot-mailcow doveadm sync -u [email protected] ssh root@<remote_ip> doveadm dsync-server -u [email protected]
Here the error is Fatal: execvp(ssh) failed: No such file or directory
and
docker-compose exec dovecot-mailcow doveadm sync -u [email protected] remote:<remote_ip
Here the error is the same as above:

Thanks in advance
Claudio

This is because "ssh" is not installed in this container environment - i encountered the same problem. I started a Bash Shell via https://mailcow.github.io/mailcow-dockerized-docs/debug-attach_service/ and installed manually via apt-get openssh-client.

But somehow i cannot sync my dovecot accounts either :/

Hi, are you able to use Doveadms TCP interface? You would need to enable the doveadm listener like this (on the remote site):

service doveadm {
  inet_listener {
    port = 19998 # or whatever
  }
}

Add a shared secret to both sites (same password):

doveadm_password = shared-secret-on-both-sides-identical

The run docker-compose exec dovecot-mailcow doveadm sync -u [email protected] tcp:remote-ip:19998

Hi,

thanks for this information – that did it for me ☺!

I added exactly

service doveadm {
inet_listener {
port = 19998
}
}
doveadm_password = shared-secret-on-both-sides-identical

and afterwards was able to sync mailboxes from one server to another without need of ssh:

docker-compose exec dovecot-mailcow doveadm sync -u [email protected] tcp::19998

Great work – again many thanks for it!

Best regards
Claudio
