Help with SPF Record for our domain.
We have an internal Exchange 2010 for our email and our domain is hosted with Heart Internet.
Our MX record has an IP address, eg: 22.214.171.124
Our main gateway is, eg: 126.96.36.199
Our domain eg: corporate.com
On heart Internet (heartinternet.uk) I have created a new TXT Record and entered:
v=spf1 a: corporate.com ip4:188.8.131.52 ~all
mxtoolbox now finds the spf record >> v=spf1 a: corporate.com ip4:184.108.40.206 ~all
Is that all I need to do? Is there anything I need to do on our internal exchange or DNS servers?
We still have a company rejecting our emails saying we don’t have an SPF record. No one else has reported this.
