--- Comment #2 from Jeremy Harris <jgh146exb@???> ---
Also, the default setting for the main-config option "hosts_require_helo" is
"*"
- so all connections will need a HELO or EHLO before accepting a MAIL.

I have to assume that the complaint is that there is no automatic connection
drop due to an excessive number of such MAILs being reveived; is that so?

It'd not be hard to count them in your mail ACL, and drop when needed.

This is surely marginal for being a security issue, and I'm downgrading it to
low importance from medium. Please justify the security aspect.
Otherwire I'll call it "wishlist".
I'm also unclear that Documentation is the right component, although
there is no obvious match - neither ACLs nor Mail Receipt are perfect.
