Re: building Dovecot in Debian 9
You might have to install the package default-libmysqlclient-dev from the Debian repo.

The 20 extension is subject to changes. If I check the Oracle DEB file for Debian 9, it seems they do use the name libmysqlclient.so, so not sure what to make of it. Double check to make sure you really installed the file libmysqlclient-dev_5.7.18-1debian9_amd64.deb from the Oracle repo. If you still have problems I might setup a Docker file with Debian 9 later tonight to check myself.

Re: building Dovecot in Debian 9
Kevin, Regarding the configuration error, your missing a package: zlib1g-dev As far as the deprecation warning, it's a bit more complicated. The source of Dovecot needs to be patched to check for the OpenSSL version and depending on the version use a different DH_generate_numbers function.

[BUG] OpenSSL function has been deprecated
In src/lib-ssl-iostream/iostream-openssl-params.c a call is made to
DH_generate_parameters. This function has been deprecated since OpenSSL 0.9.8.
With OpenSSL 1.1 compilation will throw an error.
Not sure how to send patches, I don't even know if the patch I wrote actually
works (I don't program in C, but gave it a shot anyway) but below is the patch.

If anybody knows the instruction on how to send patches, please let me know and
I follow those instructions.
