Hello all, I was experiencing problems with attachments. All zip-files I tried to send with a ticket got corrupted. Tim had the same problem with PDFs. (http://lists.otrs.org/pipermail/otrs/2005-December/009792.html). Attachments I received from customers were fine. I played around with some options about the problem. I assumed the attachments get corrupted during webupload, because if I try to open the attachments in the ticket itself they are already corrupted. I managed it working (so far) for me. There are 2 lines in otrs\Kernel\System\Web\UploadCache\FS.pm (I save the attachments in the FS): "binmode(OUT)" and "binmode(IN)". I commented them out with #binmode(OUT)... After that my zip-attachments are not corrputed any more :-)) Tim also reported that this solution solved his problem so far. Perhaps this is a problem which occurs specially under windows. Tim and I are running OTRS on windows platforms. With best regards Boris B.
