Im hoping you can help. I am wanting to set-up an SPF record for a domain name I look after. I have issues doing this, but just wondered which IP's to include. Let me tell you how we have this setup.
Exchange Server (Pub IP) sends mail to Maildefender (to get scanned), then onto recipient
The other way to receive.
My query is, do I have to include the Public IP address of my Exchange server, or just point to the SPF record to the MX records, which are all Maildefender servers?
Thanks in advance
