MXSave

MXSave is a cloud email disaster recovery service for organizations that need communication to continue during mail server outages. If a sending mail server cannot reach the primary server, the service starts failover automatically. During an outage, users can receive, reply to, forward, and compose messages through the web client or POP3/IMAP clients. Captured inbound and outbound messages are sent to the mail server when it returns. A rolling archive covers the previous 30 days, and backup is continuous with granular restore. The Enterprise Email Disaster Recovery plan is $49 a month, billed monthly, and includes one domain and 25 users; additional users cost $1.00 per user/month. It includes unlimited messages and storage, with messages spooled for up to 21 days. MXSave supports Microsoft Exchange Server, Office 365, and hosted or on-premise email servers. Desktop and mobile clients can connect using POP3, IMAP, and SMTP, including secure versions. Daily LDAP synchronization with Microsoft Active Directory updates mailboxes, distribution groups, and aliases, but cannot synchronize passwords. Messages with attachments over 35 MB are not accepted. MXSave says data and passwords are encrypted when possible and offers support tickets through its support site.

MXSave is focused on keeping email available during mail server outages and recovering messages afterward. The listed plan starts at $49 a month, with additional-user charges beyond the included 25 users.

It suits organizations seeking email access and message continuity during outages of Microsoft Exchange Server, Office 365, or hosted or on-premise mail servers. It supports desktop and mobile mail clients using standard protocols.

Overview

MXSave is an email continuity service for organizations that cannot afford to lose access to business email when a mail server goes down. It is most compelling for Exchange, Office 365, and hosted or on-premise mail environments that need users to keep communicating while service is restored.

Its strength is focused outage response: it accepts mail during disruption, keeps users connected, and returns captured messages to the primary server afterward. It is less suited to teams looking for a broad backup product or long-term email retention.

Key features

When a sending server cannot connect to the primary mail server, failover starts automatically. During the outage, users can receive, reply to, forward, and compose messages through MXSave’s web client or POP3/IMAP clients. Support for standard desktop and mobile mail clients over POP3, IMAP, and SMTP, including secure connections, gives organizations flexibility to preserve familiar workflows. The 35 MB attachment ceiling is a real constraint for teams that regularly exchange large files.

MXSave forwards inbound and outbound messages captured during an outage back to the mail server once it is online. Continuous spooling and granular restore support recovery, while the rolling archive covers the previous 30 days of email history. Those capabilities are valuable for short-term continuity and recent recovery, but the archive should not be mistaken for an unlimited historical backup.

Spooling includes anti-spam and antivirus filtering. Messages tagged by those filters are quarantined for administrator review for seven days, which adds oversight but can delay access to flagged messages. Daily LDAP synchronization with Microsoft Active Directory can update mailboxes, distribution groups, and aliases; it does not synchronize passwords, so password management remains separate.

MXSave says it works with on-premise and hosted spam-filtering services, including Barracuda, McAfee, Symantec, Mailroute, AppRiver, and Google Postini. It describes data and passwords as encrypted when possible, uses hardened Linux servers and firewalls, and supports secure mail protocols. Its Amazon data center is stated to comply with ISO 27001, HIPAA, SOC 2, and PCI DSS Level 1 programs. Customers can open support tickets and track their status through the support site.

Pricing

The Enterprise Email Disaster Recovery plan costs $49 a month, billed at $49/month. It covers one domain and includes 25 users, with additional users charged at $1.00 per user/month beyond that allowance. Unlimited messages and storage are included, and messages can be spooled for up to 21 days.

This plan is the clear fit for organizations that need outage failover and recovery without message-volume or storage caps. The included 25-user allowance suits smaller teams; larger organizations can add users, but the per-user charge should be included when estimating costs. The 21-day spooling limit matters during prolonged outages, and the 30-day rolling archive is a separate, shorter-history feature. MXSave has no free plan, so even organizations evaluating it must budget for a paid service.

Platforms

MXSave supports Android, iOS, web, and API platforms. Email access through standard POP3, IMAP, and SMTP clients also accommodates desktop and mobile mail software, including secure protocol connections.

Who it's for

MXSave is best for organizations whose priority is keeping email communication moving through a mail-server outage, especially those running Microsoft Exchange Server, Office 365, or hosted and on-premise email servers. Its automatic failover, message spooling, and return-to-server recovery address that specific operational risk.

It is a weaker fit for buyers seeking long-term archival, broad backup coverage, or support for very large attachments. The 30-day rolling history and 35 MB attachment limit define meaningful boundaries, despite unlimited storage and messages in the paid plan.

Pros and cons

• Pro: Automatic failover and the ability to send, receive, and compose during an outage help maintain communication rather than merely preserve a copy of mail.
• Pro: Unlimited messages and storage, continuous spooling, and granular restore make the Enterprise plan practical for organizations with substantial email traffic.
• Pro: Active Directory synchronization can keep mailbox, group, and alias changes aligned without manual duplication.
• Con: The plan includes only 25 users; each additional user costs $1.00 per user/month.
• Con: Messages are spooled for at most 21 days, while the rolling archive covers only the prior 30 days.
• Con: Attachments over 35 MB are not accepted, and tagged mail may remain quarantined for administrator review for seven days.

Alternatives

• AvePoint Cloud Backup is a paid alternative with Android, iOS, and web platforms; choose it if you want to request custom pricing for a different backup option.
• Spanning Backup has one all-inclusive plan, unlimited backup retention, and volume pricing, with a free trial. It is a better fit when retention length is the priority and you want pricing based on volume.
• Veeam Agent for Mac offers a free macOS edition limited to one backup job and without direct backup to object storage; choose it for a no-license-cost Mac backup job.
• VM Backup provides a free edition for two VMs per host and a 30-day fully featured trial; it fits buyers focused on virtual-machine backup rather than email continuity.
• MSP360 Backup has a free personal workstation edition for file and image-based backup with forum support; it suits personal computer backup needs rather than mail failover.
• GMvault is a free, open-source option for Linux, macOS, and Windows; choose it if those platforms and its GNU Affero General Public License v3 are appropriate.
• Synology Active Backup for SaaS is a free add-on for Synology NAS; it may suit organizations already using that self-hosted platform.
• Mailbakup offers one-time purchase backup tools for Office 365 and Google Apps on Windows or macOS; consider it when desktop-based, per-user backup purchases are preferable to ongoing outage continuity service.

Verdict

Choose MXSave if your organization needs email access to continue during server outages and wants captured messages delivered back afterward. Automatic failover, continuous spooling, and recovery are its strongest reasons to buy. Look elsewhere if you need long-term retention, larger attachments, or backup beyond email continuity.
