Dealing With Angry Clients

Hey all,

We all know the feeling of dread (eg. pucker) when a linecard goes down because someone uploaded and then rebooted into a corrupt IOS on a core router and the phones start ringing off the hook… le sigh…

Here. It. Comes.


In having to deal with this and a multitude of other issue which caused client’s “concern”, I have found that the following thoughts and ideas can shape your perspective on how to address a client’s concerns in a manner that is beneficial to both you and them and will ultimately address the overriding issue at hand, which is the primary goal. (Is some of it positive psychological manipulation? yup… Knowing and understanding human behavior is the best way to deal with any issues, even in such a temporarily client/vendor relationship as addressing a new issue)

‘findmnt’ will list all mounted filesytems or search for a filesystem. The findmnt command is able to search in /etc/fstab, /etc/mtab or proc/self/mountinfo. If device or mountpoint is not given, all filesystems are shown.
The device may be specified by device name, maj:min, filesystem LABEL or UUID, or partition PARTUUID or PARTLABEL. Note that a device name may be interpreted as a mount?point (and vice versa) if the –target or –source options are not specified. The command prints all mounted filesystems in the tree-like format by default.

You can try the following steps. First, in root SSH, run these commands:

touch /etc/blockeddomains
echo "" >> /etc/blockeddomains

Please replace with the domain name. Do not replace the “” part as that’s required, only the part with the right domain name.

In WHM > Exim Configuration Editor > Advanced Editor, put the following in the topmost box:

domainlist blocked_domains = lsearch;/etc/blockeddomains
Locate the “ROUTERS CONFIGURATION” section, and right below these lines:

driver = redirect
require_files = "+/etc/demouids"
condition = "${if eq {${lookup {$originator_uid} lsearch {/etc/demouids} {$value}}}{}{false}{true}}"
data = :fail: demo accounts are not permitted to relay email

Put the following lines:


driver = redirect
# RBL Blacklist incoming hosts
domains = blocked_domains
data = :fail: Connection rejected: SPAM source $domain is manually blacklisted.

Then, when trying to delete all messages from the spammy user you’ll see :

[root@host /home/spammyuser/public_html]# exim -bp | grep 'spammyuser' | awk '{print $3}' | xargs exim -Mrm
