Optimizing exim performance

Hi,

Recently, I experienced that exim was slow in sending outgoing mail, it was spending a lot of time in the queue, resulting in customer complains.

I came across an article in the internet to optimize the performance of exim in the server. However, the location of the exim.conf is not in /etc/exim.conf in my server. It is /etc/exim4/update-exim4.conf.conf. I just want to confirm if this is the correct file to make the configuration changes to?

Also, one of the steps given to optimize the performance is to :

Quote:

Change how many queue runners that are spawned off. In /etc/init.d/exim change: QUEUE=5m. This ensures that a new queue runner was created every 5 minutes. How often a new queue runner needs to be configured on a server depends on its load.

However there is no /etc/init.d/exim in my server, only /etc/init.d/exim4. I assume this is the correct file to edit, however, I do not find the keyword "QUEUE" in it. How do I edit this file for this option? I only see this two variables that I think are somehow related:

Code:

QUEUERUNNER='combined'
QUEUEINTERVAL='30m'

exiqsumm

EXIQSUMM(8)                                                   System Manager's Manual                                                  EXIQSUMM(8)

NAME

       exiqsumm - Summarising the queue

SYNOPSIS

       exiqsumm [-a] [-c]

DESCRIPTION

       The  exiqsumm  utility  is a Perl script which reads the output of exim -bp and produces a summary of the messages on the queue.  Thus, you
       use it by running a command such as

         exim -bp | exiqsumm

       The output consists of one line for each domain that has messages waiting for it, as in the following example:

           3   2322   74m   66m  msn.com.example

       This lists the number of messages for the domain, their total volume, and the length of time that the oldest and the newest  messages  have
       been  waiting.   By  default  the output is sorted on the domain name, but exiqsumm has the options -a and -c, which cause the output to be
       sorted by oldest message and by count of messages, respectively.

       The output of exim -bp contains the original addresses in the message, so this also applies to the output from exiqsumm.  No  domains  from
       addresses  generated  by  aliasing or forwarding are included (unless the "one_time" option of the redirect router has been used to convert
       them into 'top level' addresses).

BUGS

       This manual page needs a major re-work. If somebody knows better groff than us and has more experience in writing manual pages, any patches
       would be greatly appreciated.
