Research direction

Start by reading DirigibleConfig and TenantConfigurationKeyPolicy, then trace how generated notify: code resolves DIRIGIBLE_MAIL_SENDER before calling Mail.send(...). Define the sender and reply-to tenant behavior and check existing tenant-configuration tests; done means the effective tenant values are used, with documentation identifying which mail keys are per tenant. The optional per-tenant SMTP credentials need separate scope.

Description

enhancement

Problem

Mail is configured once per instance. Generated notify: code calls Configurations.get("DIRIGIBLE_MAIL_SENDER", "[email protected]") and then Mail.send(...), and SMTP comes from the deployment-wide DIRIGIBLE_MAIL_* keys.

None of these keys is tenant-overridable: TenantConfigurationKeyPolicy allows only its listed keys plus the DIRIGIBLE_PRINT_TEMPLATE_ prefix. DIRIGIBLE_MAIL_SENDER is not a declared DirigibleConfig key at all.

In a multitenant application every tenant's invoices, dunning letters and payslips are therefore sent from the same address, and replies go to the operator rather than to the tenant's company.

Proposal

  • Declare DIRIGIBLE_MAIL_SENDER in DirigibleConfig, and make it tenant-overridable together with a new DIRIGIBLE_MAIL_REPLY_TO (the cheap, safe part: one SMTP account, a per-tenant From display name or Reply-To).
  • Optionally: per-tenant SMTP credentials, stored as tenant configuration secrets, falling back to the instance's account.
  • Generated notify: code reads the effective, tenant-resolved value.
  • Docs: which mail keys are per tenant.
