Don't reminder notices from being sent to users who have disabled certain types of content

[rjl]

As reported by Greg Woods, reminder notices are still being issued to users who have disabled spam filtering, since items must still be spam-checked as long as at least one recipient has spam-checking enabled. These items show up as "suspected spam" even for the users with spam-filtering disabled, and while the quarantine pages conceal this, the reminder script still sees these items and issues reminder notices. In short, the send-quarantine-reminders.pl script needs to be amended to ignore such items as well.

Shouldn't the proper fix be to not quarantine them for the given user?

Fixed in [997] and [998]. It's true, though, that it would be better to set a different reference type for such users in the first place, but that's a more complicated issue with a more complicated solution.

As it happens, it doesn't matter much--the items of the unwanted type that get quarantined get safely expired in due course. This fix just prevents those items from triggering a reminder e-mail, hiding them from the user.
