And? MariaDB in Debian is 10.0 *and* it has a libmariadbclient18 package
which exim4-daemon-heavy depends on. So where's the bug? Did you hack the
depdencdies somehow?

MariaDB 10.1 isn't in Debian and if it was and it changed names one would
need a rebuild.

As said, exim4-daemon-heavy depends on libmariadbclient18, so how did you
get into this?

Of course, symlinking is always a a bad idea.

Of course, because it was built against libmysqclient, not libmariadbclient:

exim4 (4.88~RC1-1) experimental; urgency=low
[...]
  * B-d on default-libmysqlclient-dev.

Still not a bug. (default-libmysqlclient-dev) is libmariadbclient
(see https://packages.debian.org/stretch/default-libmysqlclient-dev)
