The error comes from the server, not rt-mailgate.  Also, by default, RT
writes its tmpfiles to /opt/rt4/var, not /tmp -- check that the former
is writable by your webserver.

The error comes from deep within the core tmpfile-handling module that
Perl provides.  I suspect it is caused by running out of inodes, too
many subdirectories of /tmp, or something similar filesystem-related.
