Create the file /etc/evolution-beeznest-signature.skeleton and adapt it to your needs [1]:

FULLNAME
BeezNest
Web: http://www.beeznest.net
E-mail: info@beeznest.net

Create the file /etc/evolution-gconf-signature.skeleton [2]:

<?xml version="1.0"?>
<signature name="beeznest"
format="text/plain"><filename>HOME/evolution/signatures/signature-0</filename></signature>

Use the following script, after creating the e-mail accounts.

#!/bin/bash
# Execute as user to add a personalized signature to every Evolution e-mail account

#set -x

SIGN_SKEL=/etc/evolution-beeznest-signature.skeleton
SIGN_GCONF_SKEL=/etc/evolution-gconf-signature.skeleton

# Check that signature skeleton already exists
if [ ! -r $SIGN_SKEL ]; then
        echo "No valid signature skeleton found in $SIGN_SKEL"
        exit 0
fi

# Check that signature GConf skeleton already exists
if [ ! -r $SIGN_SKEL ]; then
        echo "No valid signature GConf skeleton found in $SIGN_GCONF_SKEL"
        exit 0
fi

# Check HOME environment variable
if [ ! -z $HOME ]; then
        echo "$HOME is not set!"
        exit 0
fi

# Check default signature
if [ -d ~/evolution ]; then
        mkdir -p ~/evolution/signatures
else
        echo "~/evolution does not exist!"
        exit 0
fi
