Your JEMHC subscription drives an allocation (1st of every month) of a Capacity Plan based on the number of subscribed (active) users; as your users increase, so does message volume and data capacity. If you consume the allocated plan, inbound mail and outbound notifications stop. No data is lost, it just remains queued.

New users evaluators are initially placed on a limited capacity Starter Plan that is deliberately limited in capacity. This is to fail fast if a problem occurs (for example, a mail server delivers more mail than you expected).. We do this to help you fail fast e.g. where you start consuming all mail within a mailbox from long long ago.

If you consume your limited Starter Plan during eval, we can increase toward the plan level that your active users would give. You can request increases toward the level that your active users would allocate can be requested through support@thepluginpeople.com , should you exceed that, you would typically need to get a DataPack (see next).

Common setup problems

No Profile > Catchemail match with mail recipients

When you setup a Profile, the ‘catchemail’ address needs to match an address of incoming mail, so that JEMHC can know its supposed to process the mail, and so that addressee can be specifically excluded from storage (to avoid a mail loop). If you use a test mailbox, likely it will just not match.

Processing mail from beginning of time

When you setup a new inbound mailbox, do clear out the mailbox and/or set the mailbox to return mail ‘from this point forward’, not doing so may lead to ALL mail ever being processed (again) causing confusion (and Plan consumption leading to exhaustion).

Lack of a default SMTP server configuration

If you do not configure an outbound SMTP server, JEMHC cannot communicate to you when your inbound processing encounters a problem like the Profile > Catchemail list doesn’t match any mail addressees, to avoid data loss, the mail is not READ, to avoid repeat reading (and consumption of your plan) the inbound mail handler is taken OFFLINE. You really need a default SMTP server configured, its not used for issue related notifications without further specific configuration.

Getting more message volume and data

...

Data Packs provide an on-demand short term Message and Data volume increase. Plan Upgrades provide a 1y term to gain higher capacities normally attributed to a higher number of users on a monthly basis. Both Data Packs and Plan Upgrades are purchased out of band from Atlassian Marketplace as it has not yet matured to support such app-specific metrics (see Licensing App licensing for details).

Limiting message volume usage

...

JEMHC can’t use the built-in mailbox address provided by Atlassian, so you must use an external one. When doing so you may need allow connections from the JEMHC public IP address to to your mail service. For finer grained access control, you could setup dedicated certificates that only your configuration has.

What

...

Scripting support

Script Field Processor or Script Project Mapping Rules are not yet available. This is a important feature and is something we hope to offer between Q4 '21 - Q1 '22.

What's different?

Data Storage

As of MAR 2024 we support a default region of US as well as secondary DE region that new installation can pin their data to. As yet we do not have migration support from/to US deployment, potentially some areas can be manually exported (Profile JSON, templates etc) for reintroduction manually in a new DE deployment.

Inbound mail processing

JEMHC periodically retrieves mail from your configured mail servers over SSL for common protocols (POP/IMAP/EWSGraph). By default, JEMHC stores a rolling window of the last 100 mails in full (for mail under 10MB). This data is stored in the either AWS region us-east-1 AWS region (USA) or us-central-1 (DE) and is encrypted at-rest and in-transit. Users can opt out of email retention, but requires you to contact us to re-enable.

Info

For background, see How Jira events turn into emails and Manipulate Webhook webhook data in a Templatenotification templates.

Your Jira Cloud instance will send event data to JEMHC when changes are made to issues. JEMHC will only retain webhooks for processing where you have configured JEMHC to generate notifications for specific projects, in this way, we retain only the subset required for JEMHC to do what you have configured.

...

The structure of the JEMH Profile is very different from JEMHC. JEMH Profiles still have a lot of top-level configuration whereas JEMHC was designed with lessons-learned from JEMH whereby Project Mappings in JEMHC are Profile top-level feature, containing the majority of all configuration, Rules also then provide a subset of the Project Mappings.

Scripting support

Scripting support in JEMHC exists for:

  • Javascript PreProc Task (header manipulation)

  • Javascript Script Field Processor

  • Javascript Script Rule support in Project Mappings

  • Javascript Custom Field Default

The multi-tennant nature means that security is always at the forefront, and for that reason, scripts are restricted in what they can do, effectively they have access to the ‘issue' JSON structure, and the mail content where applicable, there are no remote calls allowed and no special custom functionality beyond javascript default scripting.

Messaging

Inbound/Outbound mail server connectivity isn’t within JEMH for Server/DC, in JEMHC, we have re-implemented all inbound/outbound mail server connectivity functionality. For example, JEMHC has OAuth authorization support, which requires specific admin actions to support, that cannot be migrated.

...

In JEMH Server/DC its possible to use regular expressions to match Project keys that should be handled through this particular Notification Mapping. In JEMHC, we avoid regular expressions and simplify things, enabling users to ‘pick’ all or nominated projects.

Transition Attachment Custom Field picker to allow

The Use the JEMH Transition Attachments Custom Field attachment picker for workflow transition screen has not yet been implemented in cloud, logged as:

  • JEMHC-3764

Status Notifications

This has not been implemented in cloud at this time.

...

We don’t support migrating audit history from JEMH Server/DC to JEMHC as JEMH Server is able to retain unlimited volumes of data. In JEMHC (with customer opt-out) we can store the most recent 100 inbound and outbound messages for your diagnostic purposes.

Issue Association

Foreign Key Issue Association configuration in JEMHC is different due to the structure of the Profile.

In short, JEMHC restricts Issue Association in a Project Mapping, scoping to the mappings selected Project.

However, the default Project Mapping will not scope to the mappings selected Project, but any non-default mappings added that inherit the Foreign Key Issue Association will scope to the non-default mappings selected Project.

For further information, see https://thepluginpeople.atlassian.net/wiki/spaces/JEMHC/pages/72908873/Understand+how+Issue+association+works#Regexp-foreign-key-association

Public REST API

JEMHC has yet to implement a public rest API as we have for DC (Use JEMH Public Rest API to Export, Import and Update profiles ). Whilst tilted as for Profiles, we also exposed a way to deliver Mail directly over REST, which was utilised by some 3rd party email client app integrations. Those integrations will need rework once we have a public API in JEMHC. We are tracking this feature interally as
