Field notes
Inboxar connects custom domains to mailboxes intended for both people and services, with IMAP, SMTP, JMAP, and a lightweight web client offered as access paths. Its API exposes mailbox creation and message sending, while a message.received webhook sends the full parsed email to a signed endpoint. The page specifies four DNS records for domain setup and names DKIM, SPF, and DMARC generation. Shared support@ and sales@ addresses are described as readable by a team.
