[Evolution] Help Needed to get Signature file working correctly

This is the second test of my signature file scrip in evolution, the signature 
seems to come out all messed up. See below:

Ralph ================================================== Gentoo Linux:
Gentoo Base System version 1.4.3.10p1 kernel-2.4.22_pre2-gss AMD
Athlon(tm) XP 2200+ AIM, YAHOO = ralphfdewitt JABBER.ORG = ralphdewitt
Signed and Encrypted mail encouraged
==================================================

The scrip that produces this is:

#!/bin/bash
echo Ralph
echo ==================================================
echo -e "Gentoo Linux:\t\t`cat /etc/gentoo-release`"
echo -e "kernel-`uname -r`\t\t`uname -p`"
echo AIM, YAHOO = ralphfdewitt JABBER.ORG = ralphdewitt
echo Signed and Encrypted mail encouraged
echo ==================================================

I do not see the double dash lines that indicate the start of a signature and 
the line breaks/spacing does not seem to work. Can someone help me get this 
script modified to produce the signature below and understand why evolution 
does not interpert this like Kmail?
