Why flagged

The package installs a setuid binary (maildrop) which is a privileged operation and a potential security risk if the binary is compromised or misused.

Triggered rules

Medium Privileged / out-of-pacman install (sudoers, setuid, or self-update) privileged_install

The package grants elevated privileges or installs an update path outside pacman: a /etc/sudoers.d rule (often passwordless), a setuid/setgid binary, or a self-update script/service that can fetch and run future code with no checksum verification. The initial install may be verified, but the ongoing privilege + update surface is a real supply-chain / privilege-escalation risk.

PKGBUILD:35 chmod u+s "${pkgdir}/usr/bin/maildrop"
