    Hi,

    I am struggling to make openAS2 work with our partner.
    Have been through many obstacles and got to the point where things seem to work, but I can't successfully send a message to the partner, and the partner is getting an error sending a message to me (although I get the message just fine, decrypted and with verified signature).

    In case of an incoming MDN for a message I send, I'm getting this in my TRACE log:

    ========BEGIN MIMEBODYPART=========
Date: Wed, 21 Jun 2017 16:19:04 GMT
Content-Type: text/plain
AS2-To: XXXXXXXXXXXX
AS2-From: YYYYYYYYYYYYYY
Transfer-Encoding: chunked
Server: Apache/2.2.17 (Unix) DAV/2
Connection: close
Error 4:libusl.c:mime_header_read_field():: Unallowed char in the value of header : 'date'. Header is corrupted.
========END MIMEBODYPART=========

    When the partner sends a message to me, he's getting a very similar complaint:

    HTTPsend: EDDINT security addition.
2pHTTP.SIGN_ENCODING    :
2pHTTP.SIGN_ENCODING    :
HTTPsend: EDDINT additional header.
HTTPsend: Uploading file(s) to http://somethingorother:10080. (total 2865 bytes).
HTTPsend: File(s) successfully uploaded.
HTTPsend: EDDINT reply signature check.
libusl.c:mime_header_read_field():: Unallowed char in the value of header : 'Date'. Header is corrupted.
libusl.c:mimepart_read_headers(): There is a bug in the logic. Error while parsing headers.

    The "elaborate" date format seems ubiquitous in the internet messaging world, and as far as I understand seems to be allowed in HTTP headers.
    What am I missing here?

    Regards
    Stan

    Hi Stan,

    1. What the value for the 'date' header?
    2. Could you please post MDN messages and Message headers from OpenAS2? Usually they are stored under <PartnerName>/mdn and <PartnerName>/msgheaders.

    Thanks && Regards,
    Nick

    Hi Nick,

    I replied, but the message disappeared without any notice about moderation or something.

    In short, thanks a lot for pointing me to the right spot - the TRACE level log apparently lied to me, because in the MDN file the date was formatted... in Polish, with a special character.
    OpenAS2 uses the Windows system regional settings for constructing headers :( Changed the regional settings and voila, no errors.

    Thank you very much again and regards
    Stan
