I do not see anything named dbmail
in standard repositories from 16.04 LTS to 19.10.
But I can find this package only for Ubuntu 10.04 LTS (EOL):
# apt-cache policy dbmail
dbmail:
Installed: (none)
Candidate: 2.2.11-1build1
Version table:
2.2.11-1build1 0

2.2.9-1ubuntu1 0

There is no such package for deb-based distros on Repology.
But for example ArchLinux has v3.2.3 from 2019-08-06, so the project is alive.
So we can download, compile and create deb-package of it from official site manually:
cd ~/Downloads
wget http://www.dbmail.org/download/3.2/dbmail-3.2.3.tar.gz
tar -xf dbmail-3.2.3.tar.gz
cd dbmail-3.2.3/
sudo apt-get update
sudo apt-get install build-essential devscripts \
automake libsieve2-dev libgmime-2.6-dev libldap2-dev libzdb-dev \
libmhash-dev libevent-dev asciidoc xmlto libpq-dev libsqlite3-dev libssl-dev
# also you need to choose from MySQLDB or MariaDB:
sudo apt-get install libmysqlclient-dev # or libmariadbclient-dev
rm debian/source/format # disable 3.0 (quilt) format
dpkg-buildpackage -uc -us -d # "-d" to ignore 'missed' automake1.9
# wait it to get compiled
# install the package
sudo apt-get install ../dbmail_*.deb
Then check it
$ dbmail-util -V | head -n1
This is dbmail 3.2.3
Note: I have never used this software, just compiled it to help you.
