Email Protocols#

Novaza Mail is a standards-compliant email server. Users can connect with any mail client that speaks IMAP, POP3, JMAP, or SMTP Submission. Webmail is not required — but it remains the quickest way to read mail from any browser without configuration.

IMAP#

IMAP keeps all messages and folders on the server, so every device sees the same mailbox state. It is the recommended protocol for most users.

Server: imap.novaza.ai
Port: 993 (implicit TLS) or 143 (STARTTLS)
Authentication: user email + password, or OAuth 2.0
Supported extensions: IDLE, CONDSTORE, QRESYNC, MOVE, ID, NAMESPACE, UIDPLUS, LIST-EXTENDED, SPECIAL-USE, SORT, THREAD, COMPRESS

POP3#

POP3 downloads messages to a single device and (optionally) deletes them from the server. It is appropriate for archival clients but not recommended for day-to-day use across multiple devices.

Server: pop.novaza.ai
Port: 995 (implicit TLS) or 110 (STARTTLS)

JMAP#

JMAP is a modern JSON-based protocol designed to replace IMAP. It is faster, easier to implement, and supports push notifications natively.

Endpoint: https://mail.novaza.ai/jmap/
Authentication: Bearer token (personal access token or OAuth 2.0)
Supported capabilities: urn:ietf:params:jmap:core, urn:ietf:params:jmap:mail, urn:ietf:params:jmap:submission, urn:ietf:params:jmap:vacationresponse

JMAP is the recommended choice for new clients and integrations. See RFC 8620 and RFC 8621 for the protocol specification.

SMTP Submission#

Outgoing mail is delivered through the submission endpoint.

Server: smtp.novaza.ai
Port: 587 (STARTTLS) or 465 (implicit TLS)
Authentication: required — user email + password, or OAuth 2.0

TLS#

All ports offer TLS. Plaintext IMAP (143), POP3 (110), and SMTP (25) accept only STARTTLS-upgraded connections. Unencrypted connections are rejected.

Rate Limits#

To protect the service from abuse, per-account rate limits apply:

Outgoing messages: 300 per hour (Community), 1,000 per hour (Professional), configurable (Enterprise)
SMTP recipients per message: 100
