Reverse proxy parameters for connection to backend servers

TLS parameters and the HTTP version for the connection from the reverse proxy to user-defined backend servers are now configurable for each virtual host.
After the TLS requirements were raised in release 7.2-2.0, it was no longer possible to connect with some technically outdated backend servers without the help of technical support. With the new parameter you can now solve the problem yourself.

Web application firewall and MS Exchange

Exception rules have been added for false positives while accessing Exchange Web Services, MAPI and Exchange Control Panel.

Sender address for system mails

Since 7.2-2.0 it is possible to set the complete sender address for notification emails and not only its domain. However if use was made of this new option, an error in the configuration generator caused problems. If mail virusscan is enabled, the scan module didn't start when the mailserver was restarted the next time and the mail server stopped to accept new emails. Furthermore invalid sender addresses were used for notifications of the attachment filter, out-of-office replies and in the groupware.

RPC-over-HTTP via reverse proxy

We planned to drop this protocol in the future, however there seems to be no alternative to access remote desktop gateways. The protocol didn't work in 7.2-2.0. Now it is available again.
