occasional stuck mail

[Noah Leaman]

I don't believe this is actually a problem with nagios but with the 
mail app being used to send notifications out. I am using Mac OS X 
Panther so it's actually by default Postfix (not Sendmail) being used. 
I also am not able to reproduce the problem consistently, but it looks 
bad anytime people aren't notified.

What is happening is once and awhile, an email notification doesn't get 
sent until another later email is sent. Nagios does report the 
notification as being sent so I believe the notify command (shown 
below) is being executed. It seems like the mail gets stuck in a mail 
queue or something and only gets sent when it sends the next mail.

I am not that familiar with how mail, sendmail, or postfix actually 
works at this level so I am a little stumped as to where to look. could 
anyone perhaps just point me in the right direction?

This is one of my email notifications commands as set up in my 
miscommands.cfg (using /usr/bin/mail):

define command{
   command_name  notify-by-email
   command_line  /usr/bin/printf "%b" "Notification Type: 
$NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: 
$HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: 
$SERVICESTATE$\n\nDate/Time: $DATETIME$\n\nAdditional 
Info:\n\n$OUTPUT$" | /usr/bin/mail -s "$NOTIFICATIONTYPE$ alert - 
$HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$" $CONTACTEMAIL$
   }
