Thanks very much @pagaille !
To provide a bit more detail…I’ve successfully connected to our Webtop mail server through Thunderbird so I know the connection details to use. I used the same connection detail in the Nextcloud Mail App and received the errors I reported.
I also wondered if this post from @mrmarkuz is still required to have Nextcloud Mail App work when connecting to our Nethserver (Webtop) mail:
No Nethserver email via Nextcloud Mail app - #22 by mrmarkuz
doveadm acl set -A Public authenticated lookup read
I’ve already confirmed that I have no Public Mailboxes. Do I still need to run this command to have a chance of having Nextcloud Mail App work?
Thank you,
