Key parts of my main.cf:
# INTERNET HOST AND DOMAIN NAMES
#
# The myhostname parameter specifies the internet hostname of this
# mail system. The default is to use the fully-qualified domain name
# from gethostname(). $myhostname is used as a default value for many
# other configuration parameters.
#
#myhostname = host.domain.tld
#myhostname = virtual.domain.tld
myhostname = assurance.hensmannassurance.net

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.tld
mydomain = hensmannassurance.net

I would appreciate any ideas or suggestions as how to fix this delivery issue. I have had little success getting Postfix to work after a failure. I usually have to rebuild my server!!

Thanks,
