NAME


vmm - command line tool to manage email domains/accounts/aliases

SYNOPSIS


vmm subcommand [argument ...]

DESCRIPTION


vmm (a virtual mail manager) is the easy to use command line tool for administrators and
postmasters to manage (alias) domains, accounts, aliases and relocated users. It allows
you to simply and quickly administer your mail server.
It's designed for Dovecot and Postfix with a PostgreSQL backend.

Each subcommand has both a long and a short form. The short form is shown enclosed in
parentheses. Both forms are case sensitive.

Most of the subcommands take one or more arguments.

ARGUMENTS


address The complete e-mail address (local-part@fqdn) of an user account, alias
address or relocated user.

destination Is either an e-mail address when used with ALIAS SUBCOMMANDS. Or a fqdn when
used with ALIASDOMAIN SUBCOMMANDS.

fqdn The fully qualified domain name - without the trailing dot - of a domain or
alias domain.

messages An integer value which specifies a quota limit in number of messages. 0
(zero) means unlimited - no quota limit for the number of messages.

option is the name of a configuration option, prefixed with the section name and a
dot. For example: misc.transport
All configuration options are described in vmm.cfg(5).

service The name of a service, commonly used with Dovecot. Supported services are:
imap, pop3, sieve and smtp.

storage Specifies a quota limit in bytes. One of the following prefixes can be
appended to the integer value: b (bytes), k (kilobytes), M (megabytes) or G
(gigabytes). 0 (zero) means unlimited - no quota limit in bytes.

transport A transport for Postfix, written as: transport: or transport:nexthop. See
transport(5) for more details.

GENERAL SUBCOMMANDS


configget (cg)
vmm configget option

This subcommand is used to display the actual value of the given configuration option.

Example:

vmm configget misc.crypt_sha512_rounds
misc.crypt_sha512_rounds = 5000

getuser (gu)
vmm getuser uid

If only the uid is available, for example from process list, the subcommand getuser will
show the user's address.

Prints a list of available subcommands with a short description to stdout. When a
subcommand was given, help for that subcommand will be displayed. After this vmm exits.

listdomains (ld)
vmm listdomains [pattern]

This subcommand lists all available domains. All domain names will be prefixed either
with `[+]', if the domain is a primary domain, or with `[-]', if it is an alias domain
name. The output can be limited with an optional pattern.

To perform a wild card search, the % character can be used at the start and/or the end of
the pattern.

Example:

This command lists all defined addresses. Addresses belonging to alias-domains are
prefixed with a '-', addresses of regular domains with a '+'. Additionally, the letters
'u', 'a', and 'r' indicate the type of each address: user, alias and relocated
respectively. The output can be limited with an optional pattern.

To perform a wild card search, the % character can be used at the start and/or the end of
the pattern.

DOMAIN SUBCOMMANDS


domainadd (da)
vmm domainadd fqdn [transport]

Adds the new domain into the database and creates the domain directory.

If the optional argument transport is given, it will override the default transport
(domain.transport) from vmm.cfg. The specified transport will be the default transport
for all new accounts in this domain.

Configuration-related behavior:

domain.auto_postmaster
When that option is set to true (default) vmm will automatically create the
postmaster account for the new domain and prompt for postmaster@fqdn's
password.

account.random_password
When the value of that option is also set to true, vmm will automatically
create the postmaster account for the new domain and print the generated
postmaster password to stdout.

Examples:

vmm domainadd support.example.com smtp:[mx1.example.com]:2025
Creating account for postmaster@support.example.com
Enter new password:
Retype new password:
vmm cs account.random_password true
vmm domainadd sales.example.com
Creating account for postmaster@sales.example.com
Generated password: pLJUQ6Xg_z

domaindelete (dd)
vmm domaindelete fqdn [force]

This subcommand deletes the domain specified by fqdn.

If there are accounts, aliases and/or relocated users assigned to the given domain, vmm
will abort the requested operation and show an error message. If you know, what you are
doing, you can specify the optional keyword force.

If you really always know what you are doing, edit your vmm.cfg and set the option
domain.force_deletion to true.

domaininfo (di)
vmm domaininfo fqdn [details]

This subcommand shows some information about the given domain.

For a more detailed information about the domain the optional argument details can be
specified. A possible details value can be one of the following six keywords:

accounts to list the e-mail addresses of all existing user accounts

aliasdomains to list all assigned alias domain names

aliases to list all available alias e-mail addresses

catchall to list all catch-all destinations

relocated to list the e-mail addresses of all relocated users

full to list all information mentioned above

Example:

vmm domaininfo sales.example.com
Domain information
------------------
Domain Name......: sales.example.com
GID..............: 70708
Domain Directory.: /srv/mail/c/70708
Quota Limit/User.: Storage: 500.00 MiB; Messages: 10,000
Active Services..: IMAP SIEVE
Transport........: lmtp:unix:private/dovecot-lmtp
Alias Domains....: 0
Accounts.........: 1
Aliases..........: 0
Relocated........: 0
Catch-All Dests..: 1

domainquota (dq)
vmm domainquota fqdn storage [messages] [force]

This subcommand is used to configure a new quota limit for the accounts of the domain -
not for the domain itself.

The default quota limit for accounts is defined in the vmm.cfg (domain.quota_bytes and
domain.quota_messages).

The new quota limit will affect only those accounts for which the limit has not been
overridden. If you want to restore the default to all accounts, you may pass the keyword
force.
When the argument messages was omitted the default number of messages 0 (zero) will be
applied.

Example:

vmm domainquota example.com 1g force

domainservices (ds)
vmm domainservices fqdn [service ...] [force]

To define which services could be used by the users of the domain — with the given fqdn
use this subcommand.

Each specified service will be enabled/usable. All other services will be
deactivated/unusable. Possible service names are: imap, pop3, sieve and smtp.
The new service set will affect only those accounts for which the set has not been
overridden. If you want to restore the default to all accounts, you may pass the keyword
force.

domaintransport (dt)
vmm domaintransport fqdn transport [force]

A new transport for the indicated domain can be set with this subcommand.

The new transport will affect only those accounts for which the transport has not been
overridden. If you want to restore the default to all accounts, you may pass the keyword
force.

Example:

vmm domaintransport support.example.com dovecot:

domainnote (do)
vmm domainnote fqdn [note]

With this subcommand, it is possible to attach a note to the specified domain. Without an
argument, an existing note is removed.

Example:

vmm do example.com Belongs to Robert

ALIAS DOMAIN SUBCOMMANDS


An alias domain is an alias for a domain that was previously added with the subcommand
domainadd. All accounts, aliases and relocated users from the domain will be also
available in the alias domain.
In the following is to be assumed that example.net is an alias for example.com.

Postfix will not accept erroneously e-mails for unknown.user@example.net and bounce them
back later to the mostly faked sender. Postfix will immediately reject all e-mails
addressed to nonexistent users.
This behavior is ensured as long as you use the recommended database queries in your
$config_directory/pgsql-*.cf configuration files.

aliasdomainadd (ada)
vmm aliasdomainadd fqdn destination

This subcommand adds the new alias domain (fqdn) to the destination domain that should be
aliased.

Example:

vmm aliasdomainadd example.net example.com

aliasdomaindelete (add)
vmm aliasdomaindelete fqdn

Use this subcommand if the alias domain fqdn should be removed.

Example:

vmm aliasdomaindelete e.g.example.com

aliasdomaininfo (adi)
vmm aliasdomaininfo fqdn

This subcommand shows to which domain the alias domain fqdn is assigned to.

Example:

vmm adi example.net
Alias domain information
------------------------
The alias domain example.net belongs to:
* example.com

aliasdomainswitch (ads)
vmm aliasdomainswitch fqdn destination

If the destination of the existing alias domain fqdn should be switched to another
destination use this subcommand.

Example:

vmm aliasdomainswitch example.name example.org

ACCOUNT SUBCOMMANDS


useradd (ua)
vmm useradd address [password]

Use this subcommand to create a new e-mail account for the given address.

If the password is not provided, vmm will prompt for it interactively. When no password
is provided and account.random_password is set to true, vmm will generate a random
password and print it to stdout after the account has been created.

Examples:

vmm ua d.user@example.com "A 5ecR3t P4s5\/\/0rd"
vmm useradd e.user@example.com
Enter new password:
Retype new password:

userdelete (ud)
vmm userdelete address [force]

Use this subcommand to delete the account with the given address.

If there are one or more aliases with an identical destination address, vmm will abort the
requested operation and show an error message. To prevent this, specify the optional
keyword force.

userinfo (ui)
vmm userinfo address [details]

This subcommand displays some information about the account specified by address.

If the optional argument details is given some more information will be displayed.
Possible values for details are:

aliases to list all alias addresses with the destination address

du to display the disk usage of the user's mail directory. In order to
summarize the disk usage each time this subcommand is executed
automatically, set account.disk_usage in your vmm.cfg to true.

vmm userservices d.user@example.com SMTP IMAP

usertransport (ut)
vmm usertransport address transport

A different transport for an account can be specified with this subcommand.

Instead of transport pass 'domain' to remove the account-specific override, causing the

to mdbox format, you can tell Postfix to retry later.

vmm ut d.user@example.com "retry:4.0.0 Mailbox being migrated"
# convert the mailbox ... then set the transport to Dovecot's lmtp
vmm ut d.user@example.com lmtp:unix:private/dovecot-lmtp

ALIAS SUBCOMMANDS
