I have everything setup for my mail server, DNS looks great, emails receive/send for everyone except icloud. I can send to my icloud account, but can’t reply back. I get the below message. Has anyone seen this before?

When I first moved my domains from G Suite (prev Google Apps) to MIAB some mail services couldn’t send emails to my MIAB system. I left it a couple of days for the DNS changes to propagate and now all is well.
I was able to get my wifes icloud.com and my son’s icloud.com email to send to the mailinabox email account. But mine still says Illegal host/domain in the bounce back from icloud.com. I’m thinking their email is hosted on a different server than mine, which is likely, and mine might work later today. I’ll keep everyone posted, just in case this happens to someone else.
Happy to tell you, after 2 days my wifes icloud account was able to send to MIAB, and then late yesterday-3 days my icloud account was able to resolve the domain for my MIAB email. It was completely a waitinf for dns to propagate issue.
