@hackage mailbox-count0.0.2

Count mailboxes in a SQL database.

Usage:

mailbox-count [OPTIONS]

Mailbox-count produces a simple count of mailboxes that exist per-domain in some SQL database. The default queries are compatible with the schema used by PostfixAdmin http://postfixadmin.sourceforge.net/, but it is possible to supply your own queries via the --summary-query and --detail-query options.

The summary report lists each domain, along with the number of mailboxes owned by that domain. The order is determined by the summary query, which lists the domains alphabetically by default.

The default detail report shows the same, but also contains a list of each individual mailbox (again in alphabetical order) belonging to the domains.

Input:

None.

Output:

Either a summary, or detailed report (with --detail) of the number of mailboxes per-domain contained in the database.

Options:

--database

The name of the database (or file, if SQLite) to which we should connect.

Default: The name of the current user (Postgres only).

--detail

Produce a detailed report listing all mailboxes by domain.

--detail-query

SQL query used to produce the detail report. This should return the set of all (domain, username) pairs. See the default value for an example.

Default: "SELECT domain,username FROM mailbox ORDER BY domain;"

--host

Hostname where the database is located (Postgres-only).

Default: None, a UNIX domain socket connection is attempted (Postgres only)

--password

Password used to connect to the database (Postgres-only).

Default: None (assumes passwordless authentication)

--port

Port number used to connect to the database (Postgres-only).

Default: None, a UNIX domain socket connection is attempted (Postgres only)

--summary-query

SQL query used to produce the summary report. This should return (domain, user count) pairs. See the default value for an example.

Default: "SELECT domain,COUNT(username) FROM mailbox GROUP BY domain ORDER BY domain;"

--username

Username used to connect to the database (Postgres-only).

Default: The current user
