Mailinabox has an option to send backups over rsync to a system. Default through port 22. Many users who want to store backups of mail in a box need a different SSH port other than 22, a change can be made
go to /mailinabox/management
nano -w backup.py
find line 17 to 20 what starts with:
|rsync_ssh_options = [|
|“–ssh-options= -i /root/.ssh/id_rsa_miab”,|
|“–rsync-options= -e \”/usr/bin/ssh -oStrictHostKeyChecking=no -oBatchMode=yes -p 22 -i /root/.ssh/id_rsa_miab\”“,|
In my setup I have to make sure the first ssh-options line is not active so put a # in front of it
Than make sure you change the -p 22 rsync option to the -p xxxx option where your SSH rsync is running. Unfortunately this cannot be set through the admin gui.
Notice: when updating mail in a box your first need to do following:
go to ./mailinabox
enter: git stash so that your changes are accepted by git and can be overwritten again. After the upgrade of mailinabox you have to make this change again.
