I’m moving from an old mail server to a new one.

On the new one, trying to transfer mailboxes from the old machine using doveadm. It fails saying it can’f find doveadm:

Does this mean the remote machine can’t fine doveadm?

(Both machines are running macOS)

I could probably transfer the mailboxes using rsync, but I thought that doveadm was a better way.

Thanks,

James.

Yeah, it means it can't find doveadm on the remote machine.
