sendmail

mail supposed to be sent from microsoft.com? I mean, the sender is bgates@microsoft.com!If we did the mail forging thing on microsoft.com instead of on someone.com this wouldn't have happened, now would it? It would have seemed like an ordinary Email... from Bill Gates... well, at least so far.Anyway, the rest is just the MID (which we will get to later) and the date of the message (the sending date) according to the server which the message was sent from. The +0000 (GMT) part means that it was sent from the Greenwich time zone. If it was sent, for example, from the +0200 time zone it would have meant that this time zone's time is actually Greenwich time plus 2 hours. Find our your time zone first so you'll be able to switch time zones and find out when was the message sent in your time.Now, on to more important things.From: bgates@microsoft.comWell, I guess this line is obvious... let's move on.Received: from some.hostname.crap.com (some.hostname.crap.com [62.0.146.225]) by alpha.someone.com (8.9.3/8.8.6) with SMTP id CAA15313 for victim@victim.com; Sat, 10 Jul 1999 02:55:46 +0300 (IDT)Okay, now this is really interesting. Now we get the sender's hostname and IP address.Note about the hostname: a dial-up(31) user will have a long and twisted hostname. For example: my hostname right now (at least when I was writing these lines) is RAS4-p97.hfa.netvision.net.il. Netvision.net.il is my ISP, and the rest is mostly crap (pay close attention to the hfa thing. Hfa stands for Haifa, which is my home town. It means that I'm connected through Netvision's Haifa server. See? Hostnames can be interesting).You must have noticed by now that the hostname we got is certainly not from microsoft.com, and that the mail server who sent this isn't exactly microsoft.com or a microsoft sub-domain(26) either, which clearly shows that this Email is completely fake.Another note about the hostname: sometimes you might not get a hostname, but you will always get a...
