- IGmailMailSender (mockable) + MailKit GmailMailSender (smtp.gmail.com:587 STARTTLS, App
Password). SendReplyService builds a threaded reply: In-Reply-To = original Message-Id,
References = stored chain + original (deduped), Subject = 'Re: ' (no double-prefix); sends,
then sets Status=Answered + AnsweredAt + stores sent body in DraftReply. Never auto-sends.
- POST /api/requests/{id}/send {body}: 200 updated RequestDto; 404 unknown; 503 MailNotConfigured;
502 MailAuthFailed (UI hint: re-enter App Password). No entity change (no migration).
- Tests (fake SMTP): threading headers, Answered transition, no-double-Re, not-configured +
auth-failure keep status; BuildMimeMessage header mapping. Live send gated on App Password.
