It's not what I see with s-nail v14.9.11 on a Debian system when using 'r' on a message with these headers: From: aut...@example.com To: rec...@example.com, rec...@example.com Cc: aut...@example.com, c...@example.com, c...@example.com It produces this: To: aut...@example.com Cc: rec...@example.com, rec...@example.com, aut...@example.com, c...@example.com, c...@example.com I.e. it didn't remove author@... from Cc. -- Geoff Clare <g.cl...@opengroup.org> The Open Group, Apex Plaza, Forbury Road, Reading, RG1 1AX, England
