chriscapoccia Posted October 21, 2005 Posted October 21, 2005 I think some spammer is gaming the system by putting spamcop headers early in the headers: http://www.spamcop.net/sc?id=z818142446z62...;action=display The reporting system complains about not being able to deterimine the source IP address. I corrected the email to http://www.spamcop.net/sc?id=z818143928...&action=display and everything was able to be parsed correctly. *MODERATOR* editied your second URL for general viewing
StevenUnderwood Posted October 21, 2005 Posted October 21, 2005 I think some spammer is gaming the system by putting spamcop headers early in the headers:34571[/snapback] Again...the ONLY issue with this spam is the lack of a blank line between the headers and body. Where the x-* headers are does not matter as they are ignored by the parser completely. The error message you got explained it quite clearly: SpamCop v 1.496 Copyright © 1998-2005, IronPort Systems, Inc. All rights reserved. No blank line delineating headers from body - abort If it were legal, the only thing you would need to do is put a blank line between: Content-Transfer-Encoding: 7bit $B!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~!y!~(B Since this message was received directly from the sender (222.149.239.180) by mx53.cesmail.net it does seem their system, or spamcop, is generating the problem. Due to the lack of other complaints, it would still appear to be the sending end. 222.149.239.180 = p4180-ipbf710marunouchi.tokyo.ocn.ne.jp looks like a corrupt end user machine to me.
chriscapoccia Posted October 21, 2005 Author Posted October 21, 2005 I didn't realize that the missing line between body and header was causing the other errors. Still, this is different from the other spams I've recieved that are missing that line. In those cases, the spamcop headers were at the very end of the message (at the first blank line). In this case they are near the beginning, so it seems like they were inserted by the sender.

You did pick that message up on the spamcop server, correct? If so, perhaps you should bring this up to JT (spamcop email admin). His contact info is in the FAQ. In response to: <a href='http://forum.spamcop.net/forums/index.php?...indpost&p=33420' target='_blank'><a href=\"http://forum.spamcop.net/forums/index.php?...indpost&p=33420\" target=\"_blank\"><a href=\"http://forum.spamcop.net/forums/index.php?...indpost&p=33420\" target=\"_blank\"><a href="http://forum.spamcop.net/forums/index.php?...indpost&p=33420" target="_blank">http://forum.spamcop.net/forums/index.php?...indpost&p=33420</a></a></a></a> just last week However, this spam seems to have a (poorly constructed) body with the blank line missing beneath the Content-Transfer-Encoding: 7bit when it reached spamcop (otherwise the x-spam* headers would be above that mess). The headers make it impossible to determine (though highly unlikely) whether the first received line Received: from unknown (x) (43.51.244.789) by 0 is valid. It seems possible that spamcop received this message from the sending system (220.150.179.55) without the required blank line after the previous headers. 33431[/snapback] Your problem in June 2004 is quite possibly the same (those are too old to view at this point): http://forum.spamcop.net/forums/index.php?...ost&p=10573
Wazoo Posted October 21, 2005 Posted October 21, 2005 I have to agree that there's no real sense of what went on with the example provided to my eyes .... just trying to recreate the sequence of events involved in conjuction with the displayed construct .... doesn't make much sense at all ... server handoff data is inserted "correctly" (i.e., above the previous server hand-off) ... yet theoretically "wrong" if one goes with the "blank line" existing 3 lines down from the top .... but then we move to the SpamAssassin stuff, which gets inserted "correctly" .. but it sees the "blank line" at the top and inserts that data "below the headers" (based on the blank line) ... Now this would (tend to) indicate that the "blank line" was inserted by JT's server ... yet, if that was the case, why aren't there a zillion posts here (and in the newsgroups) about every e-mail coming into JT's servers having this issue. OK, we could start with that there is more than one server involved, so that might take the 'zillions' down to maybe a 'crapload' ... but even that traffic level doesn't exist ... The next 'level' would have to center on things like timing, source, phase of the moon, solar flares, or even (heaven forbid) the actual spam construct ... the actual, real, untouched, raw spam would have to be looked at for that kind of analysis ... and JT has the only access to that level of detail. What I'm trying to suggest is that even Forwarding a copy to him might obscure/drop/change enough that the "real" issue couldn't be seen. The closest to the original item would be to actually look at it while still sitting in your InBox .... so if/when you try to conact JT about this, please provide enough identifying data that this specific item can be "found" ....
Jeff G. Posted October 21, 2005 Posted October 21, 2005 I think all the blades are now putting those X-spam and X-SpamCop Header Lines at the top of the Header (as they see it), rather than at the bottom. I don't know when it started, and haven't had the time to research that yet. It shouldn't matter, anyway.
chriscapoccia Posted October 21, 2005 Author Posted October 21, 2005 You did pick that message up on the spamcop server, correct? Yes. the first link (http://www.spamcop.net/sc?id=z818142446z62...;action=display) is the unmodified email that i recieved using the spamcop webmail interface. It showed up in my held mail just the way you see it.

They looked exactly the same except that in the copy in my trash, on the second line, “Delivered-To:” includes my email address. …or are you talking about something different?

Thus, the reference that only JT can determine the problem and then only if he knows exactly where to look in your folders so he can find exactly the item to which you are referring.

Jeff G. Posted October 22, 2005 Posted October 22, 2005 "around" is right. The change appears to have taken place on different blades at different times around then, probably in sequential blade order.
