After sending off a document for DocuSign signatures I received the following message:

smtp; 530 5. 1. 0 <dse_na3@docusign.net> sender rejected

Is this an issue with the receiving party and/or their phone/computer settings for receiving the email?  

I double checked the email address and it was correct.  Per DocuSign’s suggestions I even re-entered the recipient’s information, including email, as part of the “Correct” procedure in my DocuSign account.  

Any suggestions for fixing this issue?

FYI, I have successfully sent this recipient 10 to 15 docuSign emails over the past 6 months.

I am having the same issues. Comcast emails are being rejected. And another work email platform is rejecting it.

I am also experiencing this problem today with a Comcast email address.
