Bug#770281: dh-systemd: dh_systemd_enable --no-enable not working as expected

Package: dh-systemd
Severity: important
The spamassassin package contains spamd, a daemonized version of
spamassassin. This daemon is not enabled by default. In sysvinit, this
was accomplished in the init script using variables defined in
/etc/default/spamassassin. In systemd, this should be accomplished by
the use of "dh_systemd_enable --no-enable" in debian/rules. It's my
expectation that this is sufficient to install the unit file but leave
it disabled until the user explicitly enables it. However, this
doesn't seem to be working. "apt-get install spamassassin" results in
spamd getting started silently, with no output to indicate this. Details
are below and in the attached transcript.
Severity is set to important, but I think there may be justification to
raise it. Enabling daemons unexpectedly has likely security implications
and definitely violates expected/documented behavior.
The debian/rules file is at
