## How to reproduce When an inbound email has malformed sender headers (for example `From: McDonald <info@example.com` without a closing `>`), mailbox processing can raise `Mail::Field::IncompleteParseError` while resolving sender data in `MailPresenter`. ## What changed This PR hardens sender parsing in `MailPresenter` with a small, readable implementation: - Added/used a safe parser (`parse_mail_address`) that rescues `Mail::Field::ParseError` and `Mail::Field::IncompleteParseError`. - `sender_name` now uses the same safe parser path. - `original_sender` now resolves candidates in order via a compact `filter_map` flow: - `Reply-To` - `X-Original-Sender` - `From` - All three candidates are parsed as email addresses before use (including `X-Original-Sender`), and invalid values are ignored. - `notification_email_from_chatwoot?` now compares sender addresses case-insensitively (`casecmp?`) to avoid case-only mismatches. ## Test coverage Added focused presenter specs for: - malformed `From` header returns nil sender values and does not classify as notification sender - malformed `Reply-To` falls back to valid `From` - valid `X-Original-Sender` is used when present - invalid `X-Original-Sender` falls back to valid `From` - mixed-case sender address still matches configured `MAILER_SENDER_EMAIL` ## How this was tested Ran: - `bundle exec rspec spec/presenters/mail_presenter_spec.rb` - `bundle exec rubocop app/presenters/mail_presenter.rb spec/presenters/mail_presenter_spec.rb` Sentry issue: [CHATWOOT-B9Y](https://chatwoot-p3.sentry.io/issues/7005483640/)
