Mirapoint Email Appliance

Mirapoint Email Appliance is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mirapoint Email Appliance rather than just read about it. In short: Mirapoint Email Appliance was a Unix-like standards-compliant black-box e-mail server, with built-in features such as: anti-spam, anti-virus, webmail, POP, IMAP, calendar and LDAP routing. System configuration and maintenance is done through a web interface, or through SSH or telnet access to a command line interpreter (CLI).

Key takeaways

Mirapoint Email Appliance belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mirapoint Email Appliance to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mirapoint Email Appliance from memory before moving on to harder problems.

Reference excerpt

Mirapoint Email Appliance was a Unix-like standards-compliant black-box e-mail server, with built-in features such as: anti-spam, anti-virus, webmail, POP, IMAP, calendar and LDAP routing. System configuration and maintenance is done through a web interface, or through SSH or telnet access to a command line interpreter (CLI). Full access to the Unix-like Messaging Operating System (MOS) is not available. Depending on the model and configuration the appliances can be used as email routers, user mail servers, or as an all-in-one server. In October 2010, an enterprise messaging company Critical Path and Mirapoint announced their decision to merge with the combined company operating under the name of Critical Path.

Appliance Generations The first generation of Mirapoint Email Appliances were introduced in December 1998. The two models were the M100 and M1000, both of which were hardware identical. Their differences were in user count, with licensing done in software. Both platforms consisted of a 3U CPU unit, tied to a 3U high RAID array and a 3U rack mounted UPS (uninterruptible power supply). Both of these platforms initially ran Mirapoint MOS version 1.3, the first version of MOS to be released. In the initial release it was not possible to run without the UPS, later releases allowed a no UPS run state, using a license key. The second generation of Mirapoint products included both email servers and edge mail appliances. The email servers were introduced in August 1999 to replace the low-end M100 and shipped with MOS version 2.0. All the models consisted of 3U appliances with internal RAID storage. This generation featured a UPS built into the CPU head unit. The email server models were numbered SP270 (Service Provider), ES210, ES220 and ES230 (Enterprise Server). The edge mail appliances followed shortly after in December 1999 and were numbered as the MR200 (Mail Router) and the MS200 (Mail Switch). By late 2000, a minor revision was done to the 200 series, and the email servers were renamed M200 Message Servers, dropping the SP and ES designations. A high-end version of the second generation chassis was introduced, the M2000, replacing the M1000 series. The M2000 followed the M1000 specs, in offering a large external RAID array and external UPS. The new twist was clustered failover, allowing two M2000 heads to connect to a single RAID array with redundant controllers.

Acquisitions IceWarp Inc. acquired the Mirapoint software business from Synchronoss Technologies, Inc. on 30 January 2017.

Worked examples

Example 1 — a first encounter with Mirapoint Email Appliance

Start with the simplest possible case. Write down what Mirapoint Email Appliance claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mirapoint Email Appliance before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mirapoint Email Appliance ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mirapoint Email Appliance

In research: Mirapoint Email Appliance appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mirapoint Email Appliance in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mirapoint Email Appliance is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer network stubs, Server appliance, so understanding it makes those chapters shorter.
In everyday life: Look for Mirapoint Email Appliance outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
