Never, ever, really never rape rpm/dpkg/etc by cutting off
dependencies. These dependencies are there for a reason, for example
because the binary was built against mysql libs. You can't just cut
them off (unless they were dlopened like some plugins do)

That's what you want, what about your colleague next door? What about
the LDAP admin next building? What about me doing sasl?

We all have different ways of using dovecot or any other larger
software piece. You don't have to use mysql. But if the package has
been built with mysql support you need to at least leave the libs on
the system ...

It's just a matter of configuration. Killing the libs is not an
option. Leave all required libs in and just use what you want to use.

The fix is to _never_ use --nodeps in rpm and other package managers,
and to simply add the mysql libs and ignore their presence.

Unless you are setting up an embedded system and are running out of
space there is no reason not to allow mysql libs to install.
