Error expanding TNEF attachments in new 4.84.5-2

[Adri Koppes]

Kevin,

I also recently installed tnef 1.4.9.
But the new tnef 1.4.9 works fine with the older MailScanner 4.83.5.
Also the error seems to be generated by MailScanner in TNEF.pm when it
tried to create a temporary subdirectory, before the external tnef
program is run.

Adri.

Which version of tnef are you using? When I upgraded to tnef 1.4.9 I had
these problems even though I had applied the recent patches that were
posted, and all the perms looked fine.

When I went back to tnef 1.4.8, everything was OK again. I also don't
understand why tnef was touching most of these messages. I had the user
compose a single line email, composed in html, and no attachments, and
it still unpacked it. However, with tnef 1.4.8 it didn't fail at least.
