Hello,
I’m using the self-hosted version 4.5.12.
I have two different companies set up in one instance of InvoiceNinja, installed on a subdomain proposals.domainA.com. Each company has a unique domain and a unique email to match their unique domain. The first company I set up has the sender email that matches Domain A, and it sends emails via SMTP without any problems. The second company I have set up has a domain for email for Domain B, and I’m finding that email is not getting delivered to iCloud email addresses.
How can I configure so that Domain B will work under the subdomain for Domain A?
Incidentally, I used MXToolbox and found that it cannot find a DNS record or a DMARC record, but I don’t know which record I need to add where considering I’m dealing with two domain names.
Here is a video showing a brief walkthrough of my two companies and how the email is configured:
