    Do I have to look at the MSGID or at the PATH? :)

    MSGID's aren't mandatory. PATH's could be cleaned, or not reliable when re-exported from a message base on a rescan.

    So use the origin line:

    * Origin: ]\/[imac Rebirth Boss Point (2:335/364.1)

    Which should always be present, and/or the header of the mail.

    Bye, Wilfred.

    The PATH.

    Many Thank, but now I have to ask how to get the Zone? :)

    In the path you have the first node that is the originating node plus all the traversed nodes, but it's without the preceding zone.

    eg the path of this message as it was received on my point:

    @PATH: 229/426 292/854 335/364

    Many Thanks.

    Ciao!

    That's another reason why you shouldn't use the PATH... ;)

    That depends where you intercept the messages to get the information. Is it from the .pkt file or is it already in a message base?

    all the informations of the headers or an Echo message can be forged.
    :)

    If everything can be forged, your software can't know if some part or all of the message is forged, so it doesn't have to consider that. And it's not a consideration to not use the header, instead of other parts of the message. ;)

    In the between. :)
    In HPT you can intercept the single message unpacked from the bundle before the delivery to the message base, there you are in GOD MODE [(c) DOOM] and you can do all that you want with perl scripts.

    all the informations of the headers or an Echo message can be
    forged.

    You're right, but there should be someting that is injected by the main node to know where the message is originated and not forgeable by a user editor (BBS/Point/JAMNNTPD and so on), do you know about something like this?

    Are you sure that the first node of the path can be rewritten?

    Many Thanks! :)

    the Origin Line!

    MSGID should only be used for identifying a message...

    Path should only be used for noting the path of the message...

    In HPT you can intercept the single message unpacked from the bundle
    before
    the delivery to the message base, there you are in GOD MODE [(c) DOOM]

    Then you have to figure out how the header is represented in that intercepted message from HPT.

    and you can do all that you want with perl scripts.

    'perl'!? You're a masochist! ;)

    Well in an echomail message you have 4 possible sources:

    Header
    MSGID kludge
    Origin line
    PATH line

    If you don't trust any, you could compare the ones that are present. And if there are inconsistencies report/log/move-to-bad or do whatever you seem appropriate with it. I don't think it's worth it...

    Are you sure that the first node of the path can be rewritten?

    It's generated on the originating system, so someone that really wants to fiddle with it, could.

    The problem with the PATH line is the lack of zone and point fields. And they could have been stripped somewhere along the path. So the first system in the first PATH line doesn't have to be the originating system.

    Btw: The header (in a packed message) has the same limitation as the PATH, it doesn't contain the Zone and Point number of the originating system.

    So, how can I determine the originating node of a message? :D

    If you're referring to EchoMail, then FTS-4 is the spec (http://ftsc.org/docs/fts-0004.001) and it instructs you to use the Origin line to determine where a message originated.

    Ok, I see that to forge any header you need to have a full editor like golded or msged or similar, with a normal user access like BBS, QWK or NNTP you can't forge these fields.
