Reproduction Steps

Hi, I'm having a problem with BillionMail.
I set up a domain, and I have my emails, but when I send a marketing email (test) to one email address, I get this:

Time                | Subject  | Sended           | To | Success | Failed | Status | Estimated ... | Progress |
2026-06-18 07:18:48 | TEST     | support@***.fr   | 1  | 0       | 0      | Done   | --            | 0%       | 

Why !?

My domain DNS are:
Domain: "Dedicated IP added"
DNS:
MX: OK /// A record: OK /// SPF: OK /// DKIM: OK /// DMARC: OK /// PTR: Not Set

PS: I use aaPanel for my BillionMail

Observed Behavior

No error, just "Mail not sended"

Expected Behavior
