The Smart Host itself is in a reputable data center on a fixed IP address
with valid PTR and reputation ( it is my own server ) and the sender is a
fixed IP address ( it is also my own server ) but because the BO has a very
large carrier based Wireless VPN behind it I don't to allow the VPN access
to outbound SMTP ( or in fact the Internet in general ) so I effectively
restrict the VPN to using SMTP on BO with hardcoded usernames/password for
only the devices/username that I want to be able to send emails and then the
BO Smart Hosts that to my primary server to get to the 'real world'.

I would do;

	> Ideally, smarthosting could be configured in the GUI with
authentication credentials in your case

... but that obviously doesn't exist and I cannot work out how to add the
auth details after the domain in the text box so it has to be done in the
files and I do understand that this is a problem.

There was an email a while ago that talked about adding the SmartHost
information to a file that isn't modified by YUM but my archive now only
goes back to Feb. 2015 and I can't find it - or maybe that wasn't to do with
Sendmail :-)

I'd be happy to fund a feature request because this issue causes me, and
others from looking at my available archive, a lot of grief when it occurs
where we all have to race and fix the issue as a result of client
complaints.

If I whitelist the IP Address of the BO in my SmartHost the issue I face is
that the BO machine is behind my pfSense redundant routers and so is the
rest of the business network so I have a bit of a spam risk that I don't
want to deal with ( some of my business users are a worry ).

I know that this is all my own doing but it does affect other BO users so
I'm hoping that there is a solution that helps us all.....
