But your service received it two days before, and that makes the item
'old spam'.

In the 'old days' and before mailhosts, which are operational here, the
parser would use the stamp of the first good - acceptable - usable -
line coming down from the top. In this case, that line would be the
mailgate.cesmail line because the top line would be ignored because of
non-routing IP.
Now, SC actually breaks the chaining process because of 'age' before
completing the parse and never actually reports how it /would/ notify if
the item weren't old. If I forge the headers for an experimental parse
of a fresh ie not old empty item, SC will find the proper source

If reported today, reports would be sent to:

j.zano at aviso.ci

Interestingly, if I use a non-mailhost application of the parser on an
'unforged' [with respect to date] experimental empty header, it will
also find the source:

If reported today, reports would be sent to:
Re: 213.136.99.130 (Administrator of network where email originates)
j.zano at aviso.ci
assied at aviso.ci
... and if I use a non-mailhost on the original spam, with no forgery,
SC also offers to report the item, even tho' it is old

So, I would conclude from that, that the mailhosts system uses a newer
method of date determination than the non-mailhosts system.
The non-mailhost uses the first good line; the mailhosts system breaks
the parse off if it is in 'legitimate mailhost territory' and the item
becomes old.
