Need to know when this E-mail was Sent.

What does this header say? When was this E-mail sent?

I was served two days late via E-mail in one of my cases. I'd love to knock this guy out of the game right now. I've read past E-mail header questions and they were greek to me.

What does this header say? When was this E-mail sent?

Did this guy set his clock back? Why was this delayed two days? I could file for dismissal if he missed the deadline. The properties on the Word file attached seem to say it was sent on Wed.

Thanks.

It looks like it got sent on the 10th at 9:33PST.

When reading these the bottom most "Received" header is usually the first. For some reason it took a day to get from yahoo to

It looks to me like he sent it on Wednesday, then it bounced around a few internal Yahoo mailservers, then the last of these held it up for a while for some reason before sending it on to you:

Received: from nm4-vm1.bullet.mail.sp2.yahoo.com ([98.139.91.191])
by p3pismtp01-010.prod.phx3.secureserver.net with SMTP; 11 Nov 2010 23:52:25 -0700

He didn't just set his clock back, because the headers from the Yahoo servers show it being received on Wednesday too. Headers can be spoofed without too much difficulty and there is no guarantee that they are accurate, but faking them would be more involved than just setting the system to the wrong time.

You may know this, but "12 Nov 2010 06:52:25 -0000" and "11 Nov 2010 23:52:25 -0700" are the same time -- the last four digits indicate how the rest of the time is offset from GMT, so these servers are in different time zones but they are each talking about the same actual moment in time.

I'm not an expert, just a guy who has dealt with mailservers now and then.

It appears that for some reason it took two days to get from Yahoos mail server to your mail server. Smtp does not guarantee speedy delivery, nor does it actually guarantee delivery, but that it will do is keep trying for a while.

The user changing his or her clock on his or her computer would not effect the yahoo servers
nm4.bullet.mail.sp2.yahoo.com, tm10.bullet.mail.sp2.yahoo.com.

Looks like it was sent on Wednesday, November 10th via Yahoo webmail.

It bounced around yahoo for a while, then got delayed on the handoff between yahoo and secureserver.net. If the headers are untampered with, it's not possible to know whether yahoo failed to send, or secureserver failed to receive, or a combination of the two. By that I mean, yahoo could have gotten busy and not attempted to deliver, or secureserver could have gotten busy and refused to accept the mail, or might have been in the process of switching MX (mail server) records and it took a few delays until they straightened out again.

Did he set his clock back? Very unlikely. If that mail was sent via regular means his local clock wouldn't have a bearing on the timestamps for those first few hops.

Did he fake out those yahoo headers? It's possible. ** If ** (and it's a big if) he could originate the email from the machine that claims to be nm4-vm1.bullet.mail.sp2.yahoo.com ([98.139.91.191]) he could fake all the received headers up until that point (perhaps using an earlier mail as a template). Not knowing the individual I don't know whether or not that's reasonable or likely. If he or his colleagues have non-typical knowledgeable (not "expert", just the sort of thing that your regular webmail user doesn't know) about mail routing then it might be

Godaddy and others resell secureserver.net mail services, so they're a moderately big player. Yahoo is bigger. Between the two I'd suspect it's SS who delayed the mail.

My cursory glance suggests this: for some unknown reason secureserver.net got overloaded or had a transient configuration problem and didn't process mail prompty for a couple of days.

It looks like it was legitimately sent on November 10 around 9:33 AM Pacific time. Even the Yahoo DomainKeys signature matches this time (t = 1289410437 means Wed Nov 10 2010 18:33:57 GMT+0100), and this header is added by Yahoo itself and therefore wouldn't depend on the local user's clock (and even if the user somehow tried to forge headers, it's extremely unlikely that they would think of trying to forge a DomainKeys header with the correct epoch value anyway).

It looks like an issue with secureserver.net, which I assume is your mail host; if I'm reading the headers correctly, it looks like your mail server even bounced it back to Yahoo one time before it came back to you again a day later.

I agree that the headers do not obviously look fake. Typically a sending mail server will retry every 4 hours if it can't make a connection, for up to a week. I humbly suggest that your mail server was not accepting connections for 36 hours due to configuration or capacity issues, or that Yahoo could not connect due to a problem with your mail server's DNS. You should consult with your IT department.

There's a great, free tool that parses email headers out to a more readable format.

Even if the Date: line could be changed by turning back your system clock, that wouldn't affect any of the Received: lines; those are all created by the various servers the email passes through & can generally be trusted to be accurate. Unless he's a fairly accomplished hacker or has a friend who's an admin at Yahoo those're not trivial to forge these days what with all the open SMTP servers having long ago been hunted into extinction by spammers. Like everybody else says, it looks like there was a snag somewhere along the way & the email sat around a while before being delivered.

As an aside, double-check whether he is even *allowed* to serve you via email. In many jurisdictions, email is not a valid means of service.

Even if he sent it Wednesday, you didn't receive it within the time limits, if I read your question correctly. If email is valid for service, check the rules about when a message is deemed to be received. For example, things sent by post are in some sets of rules deemed to be received within 7 days of sending.

A technicality like this may not save you if the judge (?) finds you suffered no prejudice from service two days late in any event.
