I have searched the v4.6x spec pdf file for $h_HEADERNAME but it wasn't
found. Where is this all documented?

Before you replied, I tried the following in the data acl:
warn condition = ${if eq {${strlen:$h_subject}} {0}}
but then got this error for several e-mails:
failed to expand ACL string "${if eq {${strlen:$h_subject}} {0}}":
missing 2nd string in {} after "eq"
Can e-mails arrive without a subject field as opposed to an empty
subject field?
