Hello
we have the problem that attachments sent with Horde/IMP arrive as
Content-Type text/plain at receiver side and are therefore
useless/corrupted (7-Zip Files for example). If have digged around a
little bit but get lost in the MIME-Type mess. We have tried to
change the "DefaultType" directive in Apache to
"application/octet-stream" but the problem still persists.
As far as i understand Horde/IMP uses the Content-Type sent by the
User Browser or try to detect it by mime_magic/fileinfo if not set?
That is incorrect. IMP uses the Content-Type provided by the browser
first. If that content-type is application/octet-stream, only then
will mime magic be used to determine the actual MIME type.
How can i check what is sent by the browser (tcpdump search?)
How can i check what would be detected by Horde/IMP "by hand"
Can anyone confirm this behavior or is this some error in my setup
Tests done :
Send e-Mail with attachment consist of random data (dd
if=/dev/urandom of=some.file count=100) with either IE8 or Firefox
3.0.11. Check with mailclient to seen the Content-Type as
text/plain. Checked with md5sum that the resulting files are
different.
Either your browser is sending the wrong content-type or your fileinfo
db is reporting the wrong info. Neither is an IMP issue however since
both are out of our control.
