I don't know where you get your info, but qmailadmin certainly does.

Yes, you can blackhole a POP/IMAP account. Note that we had to do it this way, as older versions of vdelivermail couldn't handle comments in .qmail files.
I'm updating user.c in qmailadmin 1.2.x to use "# delete" instead. We keep the "delete" in there, as that's what qmailadmin uses later to determine that it's a blackhole (code that should be updated as well).
Note that in the unreleased 1.2.2, I've added an undocumented feature to the "create new forward" page. If you enter "#" as the forwarding address, it will create a blackhole alias.
I'll try to get 1.2.2 out soon...
