Scalable, Fast, Robust Email Servers
M-Switch (SMTP) and M-Box (POP/IMAP) are at the heart
of Isode's Internet Messaging solution.
M-Switch is a high throughput and low latency SMTP message
switch. Designed to efficienctly handle very large message loads and
queues, M-Switch work exceedingly well in demanding operational environments.
M-Box is a high performance Internet Message Store, supporting POP and
IMAP. M-Box has an optimized database design and multi-threaded architecture,
which gives high performance and allows a very large number of users
to be supported on a single server. Both are exceptionally robust and
stable and include support for fail-over clustering and Off Site Hot
Standby (Disaster Recovery).
You can read more about M-Switch here
and more about M-Box here. M-Box
performance is examined in detail in the whitepaper "Benchmarking
M-Box".
LDAP Directory Integration
Both M-Box and M-Switch use an LDAP Directory as their
preferred configuration mechanism enabling the sharing of routing, configuration
and authentication information between multiple servers as well as straightforward
integration with an ISP provisioning system.
Isode's own LDAP Directory Server, M-Vault, is recomended
for use with Isode's message servers. M-Vault is a high-performance,
high-availability server that can manage millions of entries and process
tens of thousands of queries per second. M-Vault supports fail-over
clustering and off site hot standby (Disaster Recovery).
You can read more about M-Vault here,
M-Vault performance is examined in the whitepaper "Comparative
Performance Benchmarking of M-Vault".
Mobile Email Options
Isode is committed to Open Standards and is an active
partitipant in IETF working groups. Both M-Switch and M-Box support
the IETF's standard for mail on restricted bandwidth, low storage devices
such as mobile phones (known by the aronym LEMONADE). M-Box and M-Switch
were the first LEMONADE compliant servers to be released.
LEMONADE enables an email service provider to offer clients
an effective and innovative solution to mobile email challenges utilising
existing handsets. It allows for push email (using IMAP IDLE), forwarding
email without downloading and a number of standards extensions that
optimise bandwidth usage, responsiveness and, by extension, improve
the user experience.
You can find out more about LEMONADE by reading the Isode
whitepapers "LEMONADE
Profile: The Key Standard for Mobile Messaging" and "Open
Standards: The Best Approach for Mobile Messaging". The website
www.lemonadeformobiles.com
gives more details on the profile and the companies supporting it.
Comprehensive Management Tools
A number of flexible management tools are shipped with
Isode servers, including support for monitoring and control of operational
systems and two key web-based tools; the Message Operator Interface
and the Internet Messaging Administrator.

The Message Operator Interface allows in-depth examination
of and control over messaging activity across multiple M-Switch servers
including message searching, quarantine management and statistical reporting.
The Internet Messaging Administrator for M-Box gives the
operator access to a Directory configuration browser, message store
configuration manager, shared folder manager, and user manager.
You can read more about Isode tools for messaging operational
management here.
An in-depth look at the Message Operator Interface can be found here,
and for the Internet Messaging Adminstrator, here.
Anti-Spam and Webmail
An anti-spam add-on is available for M-Switch. M-Switch Anti-Spam achieves
97%+ accuracy on 'spam' and 99% accuracy on 'possible spam' together
with a message processing rate that exceeds 50 messages per second on
a small server platform.
Integrating standard webmail packages as part Isode Internet Messaging
Solution is a straightforward task. Isode recommends (and uses internally)
the Open Source Squirrelmail package.
