Question: Why are the emails I send from Yahoo.com or Aol.com bouncing through Act! emarketing
Product Family: Swiftpage
Product: Act! emarketing
Yahoo and AOL use DMARC (Domain-based Message Authentication, Reporting & Conformance) as part of their email authentication. We sign with SPF and DKIM, but not DMARC.
We cannot fix this issue you need to use another sending email address besides Aol.com or Yahoo.com.
In short, DMARC works as follows:
- From domain in the header (From: firstname.lastname@example.org) must match with the signing domains for authentication (SPF and DKIM)
How does this affect me?
Any customer using an email address of @yahoo.com or aol.com as their sending email address will have their emails rejected from the following big ISPs and any other ISPs that implement DMARC.

Swiftpage always recommends that you send from a private domain versus a public domain (aol.com, yahoo.com, hotmail.com, ect.)
