Adobe Sign email bounces to when sending to bigpond.com domain
I have an issue with one of my signers having their email bounce back as undeliverable for an agreement I am sedning them through AdobeSign. The domain is bigpond.com.
There are no issues with other gmail signers on the agreeements and no previous issues with the bigpond.com domain. The signer is receiving my outlook emails at their bigpond.com domain email address so it appears to AdobeSign specific issue.
Any advice on what is going on and how to resolve?
