bts command from devscripts package is complimentary to reportbug. But currently it needs mta configured or mutt to send mails. It'd help a lot if bts can use reportbug.debian.org smtp server so it can send mails without configuring an mta or smarthost. When running bts --smtp-host=reportbug.debian.org it says sending mails to control@bugs.debian.org is not allowed. It'd lower the participation barrier hugely if bts can send mails without additional configurations by default like reportbug.
