>Synopsis: rc_pre() not properly checking spamd rc variables

Architecture: OpenBSD.amd64

>Description:
In revision 1.1 of /etc/rc.d/spamlogd, the rc_pre() function
ensures that spamd is enabled and not operating in blacklist-only
mode. Perfect.
However, revision 1.2 introduced a bug when the code to create
the pflog0 interface was added. Checking whether spamd is enabled
or not is essentially ignored.
>Fix:
The creation of the pflog0 interface should not be done in
rc.d/spamlogd because the interface is already created in
rc.d/pflogd (it's the exact same in fact). This seems reasonable
because pflogd is enabled by default and starts before spamlogd.
Instead, rc.d/spamlogd should just check the pflogd flag along
with the spamd flags.
