When one sets SPF/TXT record is it for the relay server/IP that sent the
email to the internet or the originating one?
For example we have a server (atuprd01.water.com) that can not be
reached via the internet. Email originating there is relayed through
our MS-Exchange server (if sent with domain water.com) or a Linux
Sendmail server (if sent with domain waterinvoice.com). All email sent
via exchange goes out an IP separate from incoming mail (MX) IP. All
email sent via Sendmail has a separate IP from incoming mail (MX) IP.
Should the SPF specify the outbound IP (e.g. 126.96.36.199 for
atlsnml2.waterinvoice.com) for the Sendmail server email or the IP/name
Source/Headers for a test message shown below in case it helps:
