It does not match a single header, let alone a *specific* header as the
one mentioned, but ALL headers. It effectively checks the entire
headers' size.
Being the one credited with suggesting it, I would rather just look at
the X-Ymail-OSG header.
I can EASILY get my MTA to block (at the gateway) any email with a
random header > xxxxx in size.
if X-Ymail-OSG is > 1024 bytes, its just about guaranteed to be spam.
