Default Maildrop: Unable to create temporary files


I have setup an ISPConfig 3 server as per:

Everything is working except receiving emails with attachments.

The error message I see is:

Sep 28 14:22:24 ispconfig3 maildrop[5387]: Unable to create temporary file.
Sep 28 14:22:24 ispconfig3 postfix/pipe[5386]: 2585740185: to=<>, orig_to=<>, relay=maildrop, delay=0.02, delays=0.01/0.01/0/0.01, dsn=4.3.0, status=deferred (temporary failure. Command output: /usr/bin/maildrop: Unable to create temporary file. )

From research so far, it seems maildrop writes to temporary files when messages are over a certain size. So, I assume the problem is that reception of emails with attachments results in Maildrop needing to write to a temp file, which it is having problems with.

Some background:
ls -la /var/tmp/
total 8
drwxrwxrwt. 2 root root 4096 Sep 28 14:22 .
drwxr-xr-x. 28 root root 4096 Sep 15 00:30 ..

ls -l `which maildrop`
-r-sr-sr-x 1 root mail 202224 Sep 14 11:08 /usr/bin/maildrop

maildrop -v

As I said before, receiving "small" emails is fine, so I presume all the "routing/filtering" functions are working fine. Everything else (web sites, ftp, etc) also work fine.

Appreciate any help.....Graeme.
