doc/web: Added a note about using Dovecot's LMTP with Postfix.
This solves issue #1.
=========
Using vmm
=========
vmm is the easy to use command-line tool of the Virtual Mail Manager.
It allows you to simply and quickly administer your mail server.
The general command syntax looks like::
vmm subcommand [argument …]
Each subcommand has both a long and a short form.
Both forms are case sensitive.
The subcommands are categorized by their functionality:
.. toctree::
:maxdepth: 1
howto/general_subcommands
howto/manage_domains
howto/manage_alias_domains
howto/manage_accounts
howto/manage_alias_addresses
howto/manage_catch-all_addresses
howto/manage_relocated_users
Most of the *subcommand*\ s take one or more *argument*\ s.
Arguments
---------
address
The complete e-mail address (*local-part*\ @\ *fqdn*) of an user account,
alias address or relocated user.

Files
-----
:command:`vmm` reads its configuration data from :file:`vmm.cfg`.
:file:`/root/vmm.cfg`
will be used when found.
:file:`/usr/local/etc/vmm.cfg`
will be used when the above file doesn't exist.
:file:`/etc/vmm.cfg`
will be used when none of the both above mentioned files exists.
