You mean when they send from MyEmma to your own domain?
Correct.

Correct.
Then the SPF record isn't used, it's spoofed. It's that simple
-
Remember that your email server believes that IT is the email server for your domain. Then it gets email from someone else claiming to be it. SPF records be darned, it knows that it didn't just send that message.

Would adding users with internal e-mail addresses to Safe Senders allow the messages to come through the filter to internal recipients as expected? That's kind of like an individualized whitelist in the O365 world, right?

I would expect so, yes.
-
That makes sense, the email is coming as if it was from that server because it believes that it itself is the master of the domain.

You can also create a transport rule that will bypass all the spam filtering heuristics and whatnot.

I wouldn't do this. A lot of spammers put the from and to address the same for this reason. If you whitelist all your internal addresses, I would think you would get a lot of spam.

Nothing gets around 100% of the rules from what I was reading on this two years ago.

I would need to see the ehaders, but I send email from a postfix relay with a valid return on my Office 365 server to other Office 365 users all the time and nothing is junked.
The only thing I did was to add the WAN IP of the location with the Postfix server as a new connector trusted by IP.

I agree this is not a good way to go and that the chances for spam go way up. In this case we're talking about 10 different internal addresses.

^^^ This ^^^ I did that for postfix and haven't had any spam flagging issues.

Very similar to what you mention here, I think this is it - https://support.e2ma.net/Resource_Center/Account_how-to/how-to-whitelist-emma.

Not exactly. That is whitelisting entire IP blocks.
