Indeed. And, there are several reasons for wanting to delay EHLO checks:
1. It allows you to determine who the intended recipient is.
2. It allows you to accept email for postmaster, eg if someone is asking why they can’t get their mail through. Or some other address by arrangement, when trying to resolve a problem.
3. It lets you log more. I’m increasingly delaying rejections to post-data when I can, so that my reject log can capture message headers.
4. And, news to me, the ACLs may not even be called!
I do one thing in the HELO ACL, which is to log the connection. I guess I should move that to another place.
