ScaiLine signs outgoing mail in production at ScaiLabs on grommunio.
Mail flow
scailine-milterfor Postfix: node enrolment in the console, signed snapshots kept on disk, signing of outgoing mail only, fail-open at every layer.- Hosted relay for Microsoft 365 (preview): attribution by Microsoft's mail-server ranges, which are now refreshed daily from Microsoft's published list, verified sender domains and the Microsoft 365 tenant ID; per-organisation certificates; shadow mode.
- The generated Exchange Online script's loop-prevention exception now matches the
X-ScaiLineheader as ScaiLine writes it.
Templates
- Visual designer with brand kits, rows and columns, directory fields, images, user photo, social icons, buttons, campaign banner and legal disclaimer; conditional blocks; previews of all four variants for any person; versions with restore.
- Images inside the message, per image or as the template default, so signatures show without the recipient allowing downloads.
Console
- Domains with a copyable verification record and an editable internal flag.
- Directory sources, attribute mappings with reset, and installation of the attribute pack in ScaiKey for tenant administrators.
- Rules with a tester; campaigns and legal entities with create, edit and delete.
- Milter nodes, API keys, and roles for individual people.
- Collapsible navigation and designer panels; a new logo.
Known limitations
- Directory sources: ScaiKey and CSV (CSV imports through support). Entra ID, LDAP and Google Workspace are planned.
- The Outlook add-in, self-service changes, click tracking for campaigns and Sent Items updates for Microsoft 365 are not available yet.
