Installation Prerequisites

You already should have installed and configured Postfix and Dovecot ≥ 2.0.0 with PostgreSQL support. You also need access to a local or remote PostgreSQL server.

Check for pgsql support in Dovecot and Postfix

To verify that your Dovecot and Postfix installation has support for PostgreSQL use the postconf and dovecot commands as shown below:

root@host:~# postconf -m | grep pgsql
root@host:~# postconf -a | grep dovecot
root@host:~# dovecot --build-options | grep postgresql
SQL drivers: mysql postgresql sqlite

vmm depends on Python (≥ 3.2) and Psycopg (≥ 2.0).

If your Dovecot and/or Postfix installation shouldn’t support PostgreSQL you could possibly fix this by installing the missing package (see below) or by recompiling the corresponding part.
