Hi,
since few month i don’t get a SMTP Connection anymore. Firewall, both Servers i.e. turn off, still no Connections. Can’t ping each other.
# telnet mailserver.com 25
Trying xx.xx.xx.xx (my IP) ...
telnet: Unable to connect to remote host: No route to host
Does anyone has an Idea?
I use Ubuntu 18.x i think and latest Bitwarden.
Login into Admin with Mail returns Error 500.
Using UFW and Ports are open.
