- When we send through their application to RingCentral fax the message never makes it to the RC servers.
- When we send directly to RC from the authorized user's mailbox the message is delivered. Only difference is EzyVet uses Amazon SES to deliver the message on behalf of the user authorized in outbound fax settings (frontdesk@"domain".com).
- We have modified our domain to include the servers for Amazon SES in the SPF record and EzyVet has confirmed we have it setup correctly.
- We have also asked them to look into possible bounce back messages on the Amazon SES portal, but they claim there aren't any. I have worked with a dedicated RC Support tech (Rhyan Uy) and he can't find anything that says the message makes it to RC.
Please Help!! Getting desperate, as we are 6 weeks into this issue.
