fix: reply-all CC's the user's own send-as alias - #91
Conversation
When reply-all is used on an email addressed to a send-as alias, extractReplyInfo doesn't know the alias belongs to the current user and includes it in the CC list. The user ends up CC'ing themselves. Filter the selected From address out of CC in buildSendOptions, where both values are known. Other aliases are left alone since they may be intentional recipients (e.g. emailing yourself at a different alias).

Sorry, something went wrong.
Greptile SummaryThis PR fixes a reply-all bug where send-as aliases were included in the CC list because Confidence Score: 4/5Safe to merge — the fix correctly prevents the alias from being sent in CC; the only remaining concern is a UX inconsistency (alias stays visible in CC chips and reappears after undo). The fix is logically sound and handles the primary bug. Score is 4 rather than 5 because the send-time-only filtering introduces a meaningful inconsistency: the compose CC field displays the alias while composing, and the undo-send composeContext stores raw cc so the alias re-surfaces if the user cancels the send. src/renderer/hooks/useComposeForm.ts — the buildSendOptions filter and the raw cc stored in composeContext (lines 324–325 and 384).

Move the from-alias CC filtering from buildSendOptions (send-time) to a useEffect on `from` changes. This fixes: - CC chips in the UI showing the user's own alias during compose - hasAnyRecipient guards using unfiltered cc (Devin review) - Undo-send restoring the alias back into CC (Greptile review)
Resolve the useComposeForm conflict and add regression coverage for selected send-as alias filtering.

@greptileai please review the latest commit. The prior UX concern is now addressed by filtering the compose CC state as soon as the asynchronous From alias resolves; all CI checks pass on the current SHA. |

Summary
Reply-all initially identifies only the account's primary address as self. When a message was sent to a Gmail send-as alias, that alias therefore remained in CC even after it was selected as From, causing users to CC themselves.
