Hi all,
I need to receive some advices regarding the configuration of QNAP Xeams package with 365 EOL services.

I want to use an internal SMTP server for unauthenticated 25 requests, and I've successfully configured the closed relay from known hosts.

Unfortunately, I receive random forgery alerts even if the messages will be successfully delivered without any kind of spam filtering (SPF OK), do you have any advices?

I've noticed that if I configure my domain in the Domain Page the emails will not be delivered, I need to keep the page blank in order to receive.

Thanks

Max,

Please refer to the Forgery Alert Exception section to bypass alerts for certain domains. Please note that build 6293 is not available publicly yet. Contact us via email if you want to upgrade to this build before it is released publicly.

I want to make a comment on your last statement about configuring the domain as a local domain in Xeams. This happens because you are most likely running in Stand-Alone mode. In this mode, Xeams will not forward emails for local domains to any other server. You have to switch the mode to Firewall mode if you want it to forward them to a different server.
