Summary

  • resolve send-as identities once per shortcut invocation
  • preserve explicit from/mailbox precedence
  • prefer original-recipient identity for reply-like flows, then the unique default identity
  • retain legacy behavior when send-as settings cannot be read

Validation

Focused mail shortcut tests were added; full CI runs in the repository pipeline.

📝 Walkthrough

Walkthrough

Mail compose commands now resolve sender identities from explicit options, send-as settings, or the primary email. New logic selects reply identities, preserves display names, excludes sender aliases from reply-all recipients, and validates fallback behavior with EML-based tests.

Changes

Compose identity resolution

Layer / File(s) Summary
Identity contracts and resolution
shortcuts/mail/helpers.go
Adds compose identity types and resolution helpers. Send-as identities support default selection, recipient matching, primary-email fallback, self-address tracking, and display-name fallback.
Compose command integration
shortcuts/mail/mail_draft_create.go, shortcuts/mail/mail_forward.go, shortcuts/mail/mail_reply.go, shortcuts/mail/mail_reply_all.go, shortcuts/mail/mail_send.go, shortcuts/mail/mail_send_receipt.go
Compose flows fetch settings/send_as, use resolved sender email and name, and include the name in generated EML From headers. Reply-all also excludes resolved self-addresses.
Identity resolution validation
shortcuts/mail/mail_compose_identity_test.go
Tests cover explicit precedence, default and recipient matching, settings failure fallback, trusted sender selection, and generated EML headers.

Priority: ⬇️ Low — Defer the mail shortcut identity update because it is a scoped send-as selection and display-name change without supplied evidence of elevated customer urgency.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to fb3a7

Mail shortcuts now select send-as identities and preserve display names, but an uncommon fallback can produce a mismatched From name and address, and dry-run output can overstate requests for explicit identities. Targeted regression coverage is also incomplete for mailbox-only and CC-only selection.

Clear the fallback name when no primary email is available.

If send-as parsing succeeds, the profile lookup returns no primary email, and no matching or unique default identity exists, this creates an identity with an empty Email and runtime.Config.UserName. +forward and +reply-all then use orig.headTo as the sender email but retain this name. The generated From header can pair the configured user name with a different mailbox address.

Set Name only when primaryEmail is non-empty, or clear it when callers use orig.headTo. Add a regression test for this fallback.

Proposed fix
- primary := composeIdentity{Email: primaryEmail, Name: composeFallbackName(runtime)}
+ primary := composeIdentity{Email: primaryEmail}
+ if primaryEmail != "" {
+   primary.Name = composeFallbackName(runtime)
+ }

As per coding guidelines, every behavior change requires a nearby regression test that fails if reverted.

Add a mailbox-only precedence case.

--from returns before the --mailbox branch. This test cannot detect a regression in explicit mailbox selection. Add a case with only --mailbox set and assert got.Email.

Add a CC-only identity matching case.

The To list already matches Alias@Example.com. The helper returns before it examines CC. Add a case with no matching To address and a matching CC address.

Keep DryRun request lists consistent with explicit identity selection.

When --from is set, or --mailbox is not me, resolveComposeIdentity returns before it fetches settings/send_as. Each DryRun now always reports that GET request. Make the DryRun request conditional on the same flags as the resolver.

  • shortcuts/mail/mail_send_receipt.go#L98-L98: add settings/send_as only when identity resolution can query send-as settings.

As per coding guidelines, “Preserve established CLI behavior, tests, lint, CI, output contracts, and public APIs unless a breaking change is explicitly requested.”
