I am wanting to switch over to Amazon SES to deliver our distribution lists. However, we have a from address that we send the emails from to the subscribers that have subscribed from that domain. However, the actual email is being sent from an entirely different domain. For example, the email is firstname.lastname@example.org but the email is being sent from def.com.
So looking at the guidelines they want the dns records to maintain both spf and sender id records.
My question is how to configure them so that this issue doesn't present a problem? Which I found at http://www.openspf.org/SPF_vs_Sender_ID
If you have published an v=spf1 policy to protect the use of your domain in the MAIL FROM and HELO addresses, Sender ID implementations that apply your policy to PRA (per RFC 4406) will reject your mail if you use your domain in the "From" (or generally PRA) header field while sending from (MAIL FROM) another system.
