How Epis Technology Provides a Reliable Email Infrastructure with Synology MailPlus High Availability

Synology

Email is still the main way that modern businesses do business every day. They use it to communicate, get approvals, set up workflows, send notifications, and talk to customers. Any time lost can hurt productivity and have a direct effect on the bottom line. That’s why Epis Technology helps businesses set up Synology MailPlus High Availability (HA), a business-grade email clustering system that is always reliable and has almost no downtime. Learn how Epis Technology supports business email.

MailPlus supports more than 1,500 employees at Synology’s own offices around the world and processes more than 170,000 emails every day. It has an amazing 99.99% uptime. To compare:

With 99.9% uptime, you can have up to 43 minutes of downtime each month.
With 99.99% uptime, that goes down to about 4 minutes a month.

Businesses that need a secure, scalable, and reliable email system with high availability can count on Epis Technology to provide the same level of resilience. See full details on MailPlus HA benefits.

Why Epis Technology Uses MailPlus HA to Keep Business Email Going

Synology MailPlus HA uses an active–active architecture, which is different from traditional active–passive email clusters that need a failover event to switch servers. Both servers work on tasks at the same time. This allows Epis Technology to offer solutions where:

Users don’t have to wait for updates or node maintenance to finish.
Email keeps coming in even when a node goes down.
Businesses can always get to important communications.

Epis Technology makes sure that MailPlus HA is set up correctly, works best for your workload, and is safe with a full continuity plan. For expert setup and deployment assistance.

Real-Time Synchronization: What Makes MailPlus Reliable

It is hard to keep two active mail servers perfectly in sync because mailboxes are always changing as employees get new messages, archive old ones, or change settings.

Synology’s engineering builds the base, and Epis Technology makes sure that it works perfectly in your production environment.

Directory Isolation for Separate User Data

Instead of a single database, MailPlus keeps each user’s data in its own folder.

This has two main benefits:

Failure isolation: If one user’s mailbox gets messed up, it doesn’t affect the whole system.
Granular synchronization: Epis Technology can sync only the data that has changed, so it doesn’t have to make copies of data that hasn’t changed.

This architecture makes sure that big companies can grow their mail systems while keeping risk low. Epis Technology uses this as a main design principle when making business email solutions.

Using ordered queues to sync tasks

Synology MailPlus uses a task-based sync system, which means that it treats every action, like sending, deleting, moving, or updating a folder, as a task.

These tasks are put in an ordered queue and worked on one at a time.

Why This Is Important for Epis Technology Clients

This architecture makes sure that data stays accurate and reliable, no matter how big the company is or how much email traffic it gets.

The most important HA feature is split-brain recovery, which is expertly handled.

When two HA servers can’t talk to each other but keep working on their own, that’s a split-brain failure. This is one of the most dangerous situations that can happen in a high-availability cluster.

Epis Technology makes sure that your MailPlus HA is set up to stop split-brain events from happening and to fix them when they do.

Controls to Stop

Synology uses layered detection logic and metadata to set rules for node priority and behavior. Epis Technology sets these up in the best way possible to lower the chance of actions that are in conflict with each other.

Automated Reconciling After a Split-Brain Event

If a split-brain does happen, MailPlus has a smart reconciliation engine that

Looks at the differences between the two servers
Looks at timestamps and the order of tasks
Looks at every action, like deleting, moving, replying, and sending new emails.
Keeps all valid content made by users
Rebuilds a mailbox state that is consistent and unified

Epis Technology makes sure that no important data is lost, even in the worst-case scenarios, by using this system.
