Outgoing mail

Admin → Settings → Outgoing mail configures how Justflows sends every email — account notices, password resets, comment moderation, form notifications, and test sends. The look of each message is set separately in Email templates.

Sender identities#

• From — the address recipients see.
• Reply-To — where replies are directed, if different.
• Envelope sender — the return-path used for bounce handling, if different again.

Transports#

Register a provider transport (SMTP or a supported provider) with its credentials. A test send returns the full transport response, so a misconfiguration is visible immediately. Transport secrets and queued retry payloads are encrypted at rest.

Delivery log and retries#

• Delivery log — every send with its status, privacy-masked so addresses are not stored in the clear.
• Dead-letter log — messages that exhausted their retries.
• Manual retry — re-send a failed message from the log.
• Per-type suppression — turn off one category of mail (for example form notifications) without disabling the rest.
• Delivery limits — cap the send rate to stay inside a provider's quota.

Attachments from plugins#

A plugin can attach up to 5 files to an email with ctx.mail.send({ attachments: [{ filename, content, contentType }] }): PDF, PNG, JPEG, CSV, plain text, or calendar, 10 MB each and 15 MB together. They go out through SMTP, sendmail, or a plugin transport. The delivery log keeps only their names, types, and sizes, so a delivery retried from the admin is sent without them. Shop uses this for PDF invoices and credit notes.

Deliverability#

The screen includes SPF, DKIM, and DMARC guidance for the sender domain so mail is less likely to be filtered. Operational access is gated by the mail:read and mail:manage capabilities.
