[Mimedefang] 'service mimedefang status' returns "multiplexor dead but pid file exists"

[Matt Smith]

Howdy all,

After upgrading to MD2.48 on a RedHat box, when running `service
mimedefang status`, it is returning the following message:
mimedefang (pid 27896) is running...
mimedefang-multiplexor dead but pid file exists
I have verified that both of the .pid files are being created in /var/run
and /var/spool/MIMEDefang/

I using the mimedefang-init script from the redhat directory in the 2.48
release, and think the problem lies at line 337 in the status() function.
My `ps ax` shows the MD processes as [mimedefang-mult] and [mimedefang],
whereas in the status() call, it is looking for mimedefang-multiplexor. 
After changing this in the init script to the shortened version, `service
mimedefang status` returns what looks to be correct:
mimedefang (pid 27896) is running...
mimedefang-mult (pid 18587 18583 27883) is running...
  0/15 ...............    0/10 .......... 237

Apart from the above error, everything is running fine (including surbl
checks - relevant to recent threads).
Is this just a system-specific thing, or is there something else going on?

Regards,
Matt
