Good morning, Bruce,
I've been reading up on the Google Gmail feedback loop (FBL):
https://support.google.com/mail/answer/6254652?hl=en&ref_topic=6259779
I'm not sure what to do next, though. The Google Gmail FBL seems intended for use with outgoing email campaigns:
"Senders will need to embed a new header called the Feedback-ID, consisting of parameters (called Identifiers) that uniquely identify their individual campaigns."
I am guessing, by "new header" Google means that I need to insert a new Feedback-ID parameter in my SmarterMail SMTP header -- do I understand that correctly?
And will this help me with the 554 messages that my SmarterMail server sends to incoming Gmail messages since April 12?
Thank you as always for your patient help. I really appreciate you, and everyone on this forum.
Eric
