DNS Configurations
Once FiercePhish, SMTP, and DKIM are installed, there are extremely important DNS entries for you to set to bypass spam filters:
In the table below, $DOMAIN represents the domain name you purchased ("domain.com"), and $SERVER_IP represents the publicly facing IP address of your server:
| Record Type | Host | Value |
|---|---|---|
| A | @ | $SERVER_IP |
| A | www | $SERVER_IP |
| A | $SERVER_IP | |
| MX | N/A | mail.$DOMAIN. |
| TXT | @ | v=spf1 a mx a:mail.$DOMAIN a:$DOMAIN ip4:$SERVER_IP ~all |
| TXT | mail._domainkey | DKIM Key from step 4 of this guide |
| TXT | _dmarc | v=DMARC1; p=none |
The automated installer will provide these values for you at the end of installation.
