sendmail_mailqueue plugin .hoststats fix.

[ahaveland]

I was baffled for a while when I could see 4 qf files in the queue directory, but munin was actually showing about 20 on the graph.
It turned out that the sendmail_mailqueue plugin was also counting any files in the .hoststat dir that began with a "q"!

On systems using host status with sendmail:
sendmail.mc contains
define(confHOST_STATUS_DIRECTORY', .hoststat')dnl

Fix for the plugin is to either add -maxdepth 1 to the find to avoid descending into subdirs, or just to exclude ".hoststat":

mspmails=find ${MSP_QUEUE} -maxdepth 1 -type f -name '[qQ]*' 2>/dev/null | wc -l
mtamails=find ${MTA_QUEUE} -maxdepth 1 -type f -name '[qQ]*' 2>/dev/null | wc -l

OR

mspmails=find ${MSP_QUEUE} -type f -name '[qQ]*' 2>/dev/null | grep -v '\.hoststat' | wc -l
mtamails=find ${MTA_QUEUE} -type f -name '[qQ]*' 2>/dev/null | grep -v '\.hoststat' | wc -l

The first option is more efficient if the queue is flat, but the second option will count mails stored in any other subdirectories.

Hope someone else finds this useful.
