there is just one to select and thas stil the same as bevore. I saved it, nothing changed
i did not remove the old webserver yet, it sits on the old node but is turned off. maybe thats the point?
Did you change DNS to point to node2 for mail and roundcubemail FQDNs.
I assume itâs about the old mailserver but if itâs stopped and on another node it shouldnât be an issue. 2 mailservers on one node are not possible as they would need to use port 25 for example.
EDIT:
Is the user domain already working?
Please also check the settings in the mail app to point to the right user domain.
a reboot of the nodes helped

Are the users shown correctly?
Maybe it helps to reconfigure mail by saving the settings.
Postfix isânt fully starting
P:S. after restarting postfox there are still no user nor email-addresses

I think that samba isnât working correctly and therefore there are no domains and mailboxes in the mail app.
Could you please check if samba shows the users on the âDomains and Usersâ page as shown here?
The users are there. I can also add a user and delte it.
I didânt touch Samba yet. Itâs still on the old node and working as always
From the error screenshots it seems that the database tables are not there.
Did you maybe stop the mail app before creating a backup and therefore the database backup didnât work?
To check the database:
runagent -m mail1 podman exec postfix sqlite3 /srv/pcdb.sqlite 'SELECT * FROM userforwards;'
ahh, yes I stopped the Mail servieces to avaid loose mails wich could come in suring the backup process 
so do you suggest I restart the mail services on the old node, make a backup again, stop the services and then restore to the new node?
PS: the output:
EDIT: my mail ist mail7 so here the correct output
runagent -m mail7 podman exec postfix sqlite3 /srv/pcdb.sqlite 'SELECT * FROM userforwards;'
Error: no container with name or ID "postfix" found: no such container
OK, postfix doesnât start at all.
Yes, I think that could help.
You could just point the port forwarding for SMTP etc to the second node which isnât reachable for mail services until you restore the mail app. So no mails should get lost.
this time Iâll get an error restoring:

Could it be that there are more mail apps on the second node and because of this configuration isnât possible?
You can check it in the app drawer on the top right after a browser refresh.
Nope there where no other mail app on this node.
But when I checked the app drawer I saw that there was a new mail app on the 2nd node. When I opend it, it asked me for configuration (maildomain and hostname).
Now mail and roundcube work.
I donât understand why there was an error and still then it works?
So last step Iâll start with moving Samba and then⊠Wish me luck

I somehow recall that Samba / AD cannot be âremovedâ. They must be destroyed.
How do I test if Samba works on the new node before I destroy it?
