This article covers the SPF and DKIM authentication processes for HENNGE One and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

2. The Create DKIM Selector Window will appear and please enter the Selector Name and chose Key Length 2048 Bits.

3. Once the DKIM Selector has been saved, please select the selector created, the TXT Record to be added to DNS will appear.

Note*: By default, the value [ t=y; ] tag will appear in the test mode, when utilizing this feature for production, please remove [ t=y; ] from the value.
