Arch Linux User Repository

I have updated the PKGBUILD file to use sha256 hashes, added support for armv7h, and changed the install path to /usr/bin. I also updated the systemd unit to allow configuration of mailhog via /etc/conf.d/mailhog and fixed the dependencies of the unit.

PKGBUILD:

pkgname=mailhog-bin
