Avaya Modular Messaging Concepts and
Planning Guide

Considerations when implementing Modular
Messaging—MSS
Modular Messaging—Avaya Message Storage Server (MSS) uses a
dedicated server and private network to isolate critical components from
reliance on the customer's IT and e-mail infrastructure. Basic voicemail
features including Call Answer and telephone retrieval of messages
operate completely independently of this infrastructure. However, certain
features rely on and interoperate with aspects of the customer's
infrastructure.
IT and e-mail infrastructure considerations when implementing Modular
Messaging—MSS are:
! The MSS and messaging application server (MAS) hosts need to
be added to the customer's DNS servers for any desktop client
usage (including Client Add-in for Microsoft Outlook and
Subscriber Options), as well as for sending networked messages
and directory updates between multiple (separate) Modular
Messaging systems or between Modular Messaging and Message
Networking systems in the customer network. Networking
between Modular Messaging or Modular Messaging and
Message Networking systems can also be done by adding these
systems to each other's /etc/hosts files without relying on DNS.
! The Modular Messaging—MSS system delivers all messages
sent outside of its Voice Mail Domain, that is, networked
messages and Notify Me messages, with the standard
SMTP/MIME e-mail protocols using the customer's IT and
e-mail infrastructure. Depending on the MSS configuration
options, these messages are sent either using DNS MX (mail
exchanger) lookups of the recipient's host.domain or using an
administered e-mail gateway which then relays the message to its
recipient. Although a configuration where networked messages
are sent directly to the destination Modular Messaging (or
Message Networking) machine and all Notify Me messages are
sent to a gateway is not explicitly supported, this behavior can be
achieved using DNS MX routing. To do this, the customer must
provide a DNS server that responds to MX queries for all hosts
with the host name of the gateway and either administer
networked machines via /etc/hosts or have the DNS server return
the actual IP address for networked Modular Messaging hosts.
! Messages sent outside a voice mail domain using SMTP/MIME
carry an e-mail "from:" address identifying the sender's Modular
Messaging mailbox, typically in the form
first.last@mmsystem.domain.company.com. If these messages
are sent through an e-mail gateway in the customer's network that
modifies outbound "from:" addresses, for example replacing the
