[Mimedefang] Timeout before data read

[Kevin A. McGrail]

I was checking some slaves on a server I've been having a lot of problems 
with lately and I was wondering about this:

md-mx-ctrl busyslaves

3 B 4476 (last=scan) (scan /var/spool/MIMEDefang/mdefang-lB4LoYOB009271)

14 B 531 (last=scan) (scan /var/spool/MIMEDefang/mdefang-lB4Lfpdm003922)

What's curious is that the mimedefang process was still hanging around and I 
run with some pretty decent timeouts:

INPUT_MAIL_FILTER(`mimedefang', 
`S=unix:/var/spool/MIMEDefang/mimedefang.sock, F=T, 
T=C:15m;S:4m;R:4m;E:10m')

Thoughts?
