[Evolution] some info please

[Richard Bown <richard g8jvm com>]

I'll probably get told off for asking, but it does need someone with a
knowledge of evo to answer.
I getting some threatening spam ,
the last part of the header looks like this:-

Date: 4 Oct 2018 17:43:38 +0200 (04/10/18 16:43:38)
From: richard g8jvm com
X-Priority: 3
Message-Id: <666322984 201810041749 g8jvm com>

Subject: [SPAM] Account Issue
Mime-Version: 1.0

Content-Transfer-Encoding: 8bit
X-Spam-Prev-Subject: Account Issue
X-Evolution-Source: 1455038713.12053.2@richard-Inspiron-N5030

Now that last line after the @ is actually the linux name of this
laptop
Is the number before it the index of the received mail or the index of
the sent mail.
Looking at sent mails that format is used on outgoing mail, is it also
used on incoming as well.?
I'm trying to determine if who ever is spoofing my email address has
got the computer name from mail I've sent to someone or a list, or from
this laptop with malware, but I haven't found anything.
Hence asking those with an expert knowledge of how evolution handle
mail.
Thanks
