I just installed ez-ipupdate from myezserver site  on sme 5.6u4 
and followed the howto up to step 3. 
when I run /sbin/e-smith/dynamic-dns/easydns start I get the following error 
"error parsing conf file "etc/easydns.conf" 
easydns.conf file
service-type=easydns
name=xxxx:xxxx
host=xxxx.com
mx=xxxx.com&backmx=YES
wildcard
interface=eth1
cache-file=/tmp/ez-ipudate.cache
I have rebooted the system several times but that does not seem to work. your help will be appreciated. 
thanks 
john
