[Pkg-exim4-users] Trouble using exim4 as smart-host

[Alan McConnell]

Assembled Wisdom!

My difficulty has come about because of my recent install of Debian jessie; the
process I am about to describe worked fine with  wheezy.

Here is the content of my /etc/exim4/update-exim4.conf.conf, created when I last
ran   dpkg-reconfigure exim4-config :

dc_eximconfig_configtype='smarthost'
dc_other_hostnames='127.0.0.1;alanmcc.localdomain'
dc_local_interfaces='127.0.0.1'
dc_readhost='alanmcc.localdomain'
dc_relay_domains=''
dc_minimaldns='false'
dc_relay_nets=''
dc_smarthost='mail.his.com::587'
CFILEMODE='644'
dc_use_split_config='false'
dc_hide_mailname='true'
dc_mailname_in_oh='true'
dc_localdelivery='mail_spool'

NB:  'alanmcc.localdomain'  is my box here at home.  'his.com' is Heller Information
Services, a long-time ISP and mail and web services provider here in MD.

Finally, the _problem_:  I send mail, using mutt, to   alan at his.com  .  It arrives
there fine.  This shows that I am accepted by his.com, i.e. my password to his.com
is OK.  But when I send mail to other addresses, e.g. my gmail account, it is not
relayed on as it should be by a smart-host.

I have queried Heller, and received unhelpful responses: "You have upgraded on your
own responsibility, we don't know exim or mutt"

I don't know very much about exim4.  The documentation says that I, as root, can
add or modify the update-exim4.conf.conf .  So my question is: does the above
update-exim4.conf.conf look as it should?  Should something be changed? a line added?

I hope that people here who also use smart-hosts will give me some good advice/tips.
