For future reference it is also possible to use dpkg to remove postfix
ignoring the dependency and then install it again satisfying the
dependency.
dpkg --purge --force-depends postfix
...verify /etc/postfix/ and other locations are clean...
apt-get install postfix
...configure it as desired...
That would have avoided the clever use of an alternate MTA such as
nullmailer as a dependency placeholder. :-)

It was there. I ran through a test just now. dpkg --purge as above
and the installed. Selected Satellite. I see this:
Please specify a domain, host, host:port, [address] or [address]:port. Use
the form
[destination] to turn off MX lookups. Leave this blank for no relay host.
Do not specify more than one host.
The relayhost parameter specifies the default host to send mail to when no
entry is
matched in the optional transport(5) table. When no relay host is given,
mail is routed
directly to the destination.
SMTP relay host (blank for none):
When I specified the following to that form:
smtp.proulx.com:587
It resulted in this configuration entry.
root@turmoil:~# postconf relayhost
relayhost = smtp.proulx.com:587
And so it is possible to use that Debian specific installation
option. Any more details here should be on a Debian specific mailing
list.
However personally I always simply choose Internet Site and then
configure everything I want on top of that template. It's a good
default to start from but I always want more specific customizations
on top of it.
