Now I've got: SMTP send failure: (550, 'No valid sender found in the From:, Sender: and Reply-to: headers'). Do you want to retry (or else save the report and exit)? [Y|n|q|?]? ?
Can I simply send the generated message via my favorite e-mail client? (The maintainer address is different than the address for the mailing list)
