MarsSeed [1] filed a deletion request for exim-mysql [2]: Orphaned package, last updated in 2018.
Modified build of Arch/community/exim, to use mariadb instead of sqlite. Seems not needed. There are no user comments since 2015. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/exim-mysql/
