Mobile “quarantine” app discontinued

In 2014, we introduced an app for Android and iOS that allowed email users to do basic quarantine management (e.g. view quarantined messages and release them). Over the last few years, app usage has significantly decreased, and the indications are that the apps are not providing much value to partners or users.

The Android app was quietly retired a while ago, when Google deployed some changes to the Play Store. The iOS app stopped working a few weeks ago when we introduced some new security improvements.

We have decided to discontinue the app. The iOS app will be removed from the App Store soon – while it will still be available on iPhones that already have the app, we will not be fixing the issue recently introduced, so it should be removed, and the normal control panel interface used instead.

At this time, we do not have plans to develop a new Android, iOS, or iPadOS app. If you have opinions about this, we’d love to hear from you – please reach out to your account manager.

Note that the app is (and always has been) open-source. You’re welcome to update the app yourself if you’d like to have a custom one. Note that this will at minimum require changing the authentication mechanism, and the way that messages are accessed (to either our newer API, or directly via IMAP).

Important Upcoming Changes (HC & LC)

There are three upcoming changes that you should be aware of, and may require you to update your servers and/or integrations.

SMTP AUTH must use TLS (Outgoing Filter, HC & LC)

In May, we will start requiring all SMTP AUTH connections (ie. the outgoing filter where you use a username and password, rather than authorising all connections from an IP) to use TLS. This applies to both SpamExperts Hosted Cloud and SpamExperts Local Cloud. Using TLS ensures that anyone that has access to your network traffic is unable to read the SMTP AUTH credentials. If you are not already using TLS, please make that change as soon as possible.

Removing support for HTTP, adding HTTP Redirect (Control Panel & API HC & LC)

Later this year, we will be removing support for accessing both the control panel and the APIs using plain (unencrypted) HTTP. All HTTP requests will respond with a standard “301” redirect response to the HTTPS version. If you are not already using HTTPS requests, we recommend that you change to do so as soon as possible. While most software will automatically follow redirects, you may need to take particular care with any custom API integrations you have created.

We will provide specific dates for when this change will go live closer to the time, but we strongly recommend changing to only use HTTPS as soon as you can.

Hosted Cloud IP Change (LDAP Sync & Authorisation, Continuity)

The IP addresses used to do LDAP authorisation, LDAP syncing, and send messages through the “Continuity” feature of the app has changed. The new IP addresses are and 2001:978:2:6::20:10 – (and similar names) resolve to these new addresses, but if you have the IP addresses in your firewall, you will need to replace the old addresses ( and 2001:1af8:4500:a034:101::2) with the new ones.

This change is effective as of Sunday the 17th of April 2022. We apologise that we missed informing you of this change in advance.

SpamExperts Hosted Cloud Delivery IPs Updated

We’re continually working to make it easier to onboard to SpamExperts Hosted Cloud and maintain the configuration. One piece of feedback we get is that it’s difficult to manage the large number of IP addresses that filtered incoming mail will come from – configuring the firewall when first adding a domain, and then managing the firewall to handle any updates. While using the hostname ensures that you always have the latest list, we understand that having a large list is inconvenient.

We’ve cut the number of IP addresses by more than 95%, so will now only load 14 IP addresses (and if you can’t use for some reason, you only have to enter 14 addresses into your firewall).

N-able SpamExperts Local Cloud Release Notes July 20th, 2021

Operating System upgrade

Over the next 6-8 weeks, we will be upgrading all SpamExperts Local Clouds to a newer OS version. There will be some disruption to the clusters as part of this upgrade, but this will not impact filtering. The update will be actioned during the scheduled update period for each cluster.

After the upgrade is complete, we very strongly recommend that you reboot your servers, one by one, in order to ensure that the latest kernel version is active. We will notify you after the upgrade is complete with more recommendations about how to most safely & efficiently reboot all the servers in the cluster.

The OS upgrade will also deploy the latest build, which includes several other fixes & improvements. It also enables the inclusion of improvements to Email Scout Reports, and a new custom actions feature, that will be released over the next few weeks – expect a post with more details on those soon.

Removal of outdated functionality

To improve the performance & security of the app, we are removing some pages that were replaced some time ago, and were only accessible via a saved bookmark or directly entering the URL. The addresses will now redirect to the replacement pages. These are:

  • The old “Train non-spam” and “Train spam” pages (these redirect to the “Train messages” page)
  • The old archive search page (this redirects to the “Incoming Archive search” page)

Similarly, some functionality is being removed from the old, hidden, queue page and old log search pages:

  • View message (replaced by an action to view the message from the new log search page)
  • Train message (replaced by an action to train the message from the new log search page)
  • Delete message (replaced by an action to delete the message from the new log search page)

TLS required for IMAP connections

IMAP connections to the quarantine server will now require a connection secured with TLS. This can be explicit (ie. using STARTTLS with a port 143 connection) or implicit (ie. connecting to port 993).

Detailed changelog

This update resolves the following issues:

  • #2966 An error where archived messages that could not be immediately stored on the storage node would continue to be queued on the filtering server (MMA-5938)
  • #2992 Logging tables on clusters that have converted to the newer database engine could fail to store entries in extremely rare circumstances (MMA-5906)
  • #2954 Very long running archive indexing jobs could start to expire the index before the indexing job was complete (MMA-5658)
  • #2989 An issue where outgoing filter ESR reports could be sent based on the wrong time zone (MMA-5904)
  • #143 An error that could cause rotated logs to have an incorrect owner
  • #1642 An issue where after executing an action (e.g. whitelisting a sender) in the app, the user would be unable to execute a second action without reloading (MMA-5922)
  • #142 An error that could cause custom TLS certificates to be replaced with Lets Encrypt certificates during the update process (MMA-5921)
  • #2976 A rare issue that could cause a negative AV scan result to be incorrectly cached when scanning remote files (MMA-4495)
  • #3053 An error when previewing a quarantined message with invalid character encoding (MMA-5997)

This update also includes the following improvements:

  • #382 Upgraded to PHP 7.3
  • #1516, #1518, #1648, #1580, #1541, #2956 Improved app loading speed by removing flags for fully deployed features
  • #141, #2968 Added support for Protection Report generation as a dedicated server role (MMA-4964)
  • #3039 Reduced the amount of space required to track the archive disk space used by domains (MMA-5789)
  • #2461 Added a safety check that ensures that only valid characters can be used for table names when specified in executing maintenance scripts (MMA-5108)
  • #2952 Reduced disk use in logging scheduled maintenance job output
  • #2823 Removing outdated quarantine accounts is delayed if there are replication issues on the quarantine server
  • #2965 Parsing non-standard ISO files has been improved (MMA-5918)
  • #2684 Outgoing email that will fail an SPF check downstream will again score more highly in the classification decision (MMA-5611)
  • #1635 The “locked account notification” template editor now has a UI that is consistent with the other template editors (MMA-5723)

N-able Spam Experts: April 13 Features and Updates Release

What’s new:

We have improved consistency by upgrading the legacy Protection Reports to use the current message view when using the subject link (MMA-5333).

Improved the Mailboxes, Mailbox Aliases, Domain Aliases, Templates, Destinations, Whitelist, Blacklist, Custom Filtering Rules, Custom Filtering Actions, and many other pages so that results are displayed on page load, without having to use the “show results” button (MMA-3694).

Admins can now select which activation template is used when Email Scout Reports are created. Users can use this to default to a different language, or to welcome new mailboxes using content specific to their service or brand (MMA-1421).

Viewing message logs across multiple domains is now much simpler, with the addition to the incoming & outgoing log search pages of filtering by admin (MMA-3318).

Training messages in the app is now simpler, with a fresh design of the training page, combining training all types of incorrectly classified messages in one location (MMA-680).
