Advanced settings

In this section you can change advanced settings applied for the SMTP task:

Search for sender's originating IP address in headers - If enabled, ESET Mail Security looks for originating IP address in message headers so that different protection modules (Antispam and others) can use it. In case your organization is separated from the internet by a Proxy, Gateway or Edge Transport Server, email massages appear to arrive from single IP address (usually an internal one). It is common that on the outside server (for example Edge Transport in DMZ) where senders IP address is known, this IP address is written into the message headers of email message that is being received. Value specified in Header with the originating IP field below is the header that ESET Mail Security looks for in message headers.

Header with the originating IP - Is the header that ESET Mail Security looks for in message headers. Default is X-Originating-IP, but if you are using third party or custom tools that use different header, change it to an appropriate one.
