Mail, domains & deliverability
How this is scored
How well the mailbox itself works: custom domains and their DNS set-up, aliases, catch-all, shared and functional mailboxes, distribution lists, mailbox and attachment size limits, IMAP, POP3, SMTP and Exchange ActiveSync or MAPI for Outlook, web and mobile apps, spam and malware filtering, SPF, DKIM, DMARC and MTA-STS, out-of-office and server-side rules, send limits, and the delivery reputation of the sending infrastructure. A self-hosted groupware is judged on the mail server it ships; a suite whose mail app is only a client for another server scores at the level of that client.
0 — No mailbox at all; a product that only sends transactional mail or only reads another provider's mail without a server of its own or a documented one to pair it with.
3 — Mailboxes on a custom domain with IMAP and SMTP and a webmail; aliases, shared mailboxes, filtering and DKIM or DMARC are basic or not described.
5 — Several custom domains with a documented DNS set-up, aliases and distribution lists, shared or functional mailboxes, IMAP and SMTP plus mobile apps, spam and malware filtering, SPF and DKIM signing, mailbox size per plan stated, server-side rules and out-of-office replies.
8 — Exchange ActiveSync or native Outlook (MAPI) support, DMARC reporting and MTA-STS or DANE, catch-all and plus addressing, delegated access and send-as, quarantine an admin can review, send and attachment limits stated, and the deliverability of the outbound infrastructure documented.
10 — A mail platform a large organisation runs on: every protocol above with feature parity stated per client, inbound and outbound gateways configurable, journaling, DANE and MTA-STS enforced, delivery monitoring and bounce analysis for admins, and mail flow documented end to end.
The Data Protection Officer
Custom-domain mailboxes with documented IMAP on port 993 with SSL and SMTP on 587 with STARTTLS, a webmail at the kSuite mail app, mobile apps, SPF, DKIM and DMARC filters, anti-spam and anti-virus, unlimited mail storage on paid plans and stated send and attachment limits. We found no public information on shared or functional mailboxes, aliases, distribution lists, catch-all, out-of-office and server-side rules, or on ActiveSync or MAPI — New Outlook is configured over IMAP. The mailbox itself is solid and the OpenPGP/ECC encryption is exactly what a referral letter between doctors needs; what a nine-practice group would run centrally is not described. 2 3 7 13 20
