Postie and “Unauthorized Post Attempt from”

@wayneallen-1 our team has used postie for a while now. We’ve recently had to migrate the site that is using postie from our old system to new.

Now live and on the new system, I am unable to submit a form via the site without it being flagged as ‘Unauthorized Post Attempt from’, which is an email to the appropriate recipients. The submission is also NOT being stored as a draft in ‘posts.’

The following has been done via our Postie settings, but still no luck. Please advise. Your help will be most appreciated:

* User > roles that can post, all roles of the email in question are checked
* User > email has been added to ‘authorized addresses’

Thanks,
gail
