a821 [1] filed a deletion request for qmail-qfilter [2]: Abandoned package from 2015. One vote. No reverse depends. `qmail` was deleted long ago, so I don't think this software would work.
(also, there's no package() function, so makepkg throws an error) [1] https://aur.archlinux.org/account/a821/ [2] https://aur.archlinux.org/pkgbase/qmail-qfilter/
