Hello Aki,

yes, that's it - thank you.
For reference this works:

sudo doveadm import -u destination@company.net maildir:/var/vmail/company.net/some.name/Maildir  some_name ALL

Thanks again

Carsten

Subject: Merging mailboxes with doveadm

Hello,

I am trying to merge(=copy) all mails of all user mailboxes into one mailbox for one-time archival purposes.

The command I am using is

 sudo doveadm -v copy -A archive@somedomain.net ALL


The error I get for every mailbox is:

doveadm(someuser1@somedomain.net): Error: Can't open mailbox 'a@somedomain.net': Mailbox doesn't exist: archive@somedomain.net

doveadm(someuser2@somedomain.net): Error: Can't open mailbox 'a@somedomain.net': Mailbox doesn't exist: archive@somedomain.net

[etc...]

I don't exactly understand why. I think I am don't understand the 'destination' parameter correctly, so somebody can enlighten me, please?

Thank you


Carsten
