exim graphs

tom — Wed, 25 Feb 2009 21:21:27 +0000

Because I did not found a tool to create graphs (the way I want it)
from exim logs, I wrote a little bash script that suits my needs.

Example graph:

Download: exim_rrd-0.9.5.1 (updated 2009-03-07 [bugfix])

I’m not a programmer, so the script can be improved – no question : )
If you have any hints, please tell me.

Usage: run as cronjob, i.e.
# mail statistic */5 * * * * /usr/local/bin/exim_rrd > /dev/null 2> /dev/null

exim / implementing greylisting without db

tom — Wed, 28 Mar 2007 16:03:36 +0000

I had greylisting running for a while with a little perl script, that only worked with ip-addresses. As spam is growing an growing, I wanted to use the whole triplet (ip/sender/recipient) for the filter.

As I did not want to use a database backend, the decision led to greylistd – an easy configurable daemon. I needed the packages for (open)SuSE, that can be found in openSuSE’s software repository.

After installing it and checking the basics at /etc/greylistd/config, you have to add a little code to your acls in exim.conf, i.e.:

defer message = greylisted $sender_host_address. please try again later condition = ${readsocket{/var/run/greylistd/socket}\ {--grey $sender_host_address $sender_address $local_part@$domain} {5s}{}{false}}

That was all I had to do to get it working. It’s advisable to add some hosts, that are known for problems with greylisting, not to be checked. Therefor you have to extend your acl:

defer message = greylisted $sender_host_address. please try again later !hosts = : ${if exists {/etc/greylistd/whitelist-hosts}\ {/etc/greylistd/whitelist-hosts}{}} : \ ${if exists {/var/lib/greylistd/whitelist-hosts}\ {/var/lib/greylistd/whitelist-hosts}{}} condition = ${readsocket{/var/run/greylistd/socket}\ {--grey $sender_host_address $sender_address $local_part@$domain} {5s}{}{false}}

Many thanks for the documentations from Arne Schirmacher and Ben Charlton.

exim / remove (all) frozen messages from queue

tom — Thu, 22 Mar 2007 18:03:35 +0000

Just a quick & dirty hack to delete frozen messages for a single / some recipient(s)…

#!/bin/bash # # what are we searching for? # (part of the email-address) SEARCH="anyrecipient.tld" # # exim-bin EXIM=`which exim` # # execute (frozen messages only).. $EXIM -Mrm $(mailq | grep $SEARCH -B1 | grep frozen |cut -c 11-27)

Thanks to Mark -> this can be done a lot of easier if you want to kill all frozen messages:

exiqgrep -z -i | xargs exim -Mrm

If you want to do this only for some domains / email-addresses, use the first example.
