Purpose

This package contains changes necessary to use PostgreSql rather than Mysql. It is based upon the following installation tutorial:

• https://thomas-leister.de/mailserver-debian-buster/

DISCLAIMER: Take this data with a grain of salt. If you don't know what you're doing, don't to it !!! Since I haven't tried to install a mailserver again it's possibly that some information might have slipped although I don't believe so.

• ./dovecot - changes for the dovecot installation
