SMTP inbound authentication

Dear Forum,

I'm looking for a way to restrict mailservers in sending mail to Netweaver systems. To be more precise, I want Netweaver to accept mail from only 1 mailserver (like in exchange, where I can define which servers are allowed to relay mail). I read about using X.509 certificates and the optional parameter vclient, but at first glance this looks like an overkill to me.

Is there any easier way to get this solved?

Thanks and best regards

Frank

    Hi,

    One obvious solution is to use a software firewall with a rule accepting only SMTP connexions from your mailserver IP.

    On Windows, the firewall is even standard...

    Hi,

    thanks for your answer. I was hoping there's a possibility to configure this in the smtp server itself, but as you suggested, a firewall will do the job perhaps even better.

    Regards,
