Important parameters to configure in ESA for inbound email

[techguy]

Hi,

I am looking for any guidelines/suggestions to configure all the important features in order to receive email (inbound emails).

Thank you.

You can start with the CVD (Cisco Validated Design) on the ESA:

https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/Aug2014/CVD-EmailSecurityUsingCiscoESADesignGuide-AUG14.pdf

That gives you all you need to get your ESA running. After that all is highly dependent on what you want to achieve.

You can also reference this TechNote:

https://www.cisco.com/c/en/us/support/docs/security/cloud-email-security/210890-Configuration-Best-Practices-for-CES-ESA.html

While it was written for Cloud Email Security (CES) specific, the same can still apply to administrator of on-prem/hardware/virtual ESA.
