Hello, I am looking for something like: send2-hook . 'unset_header Reply-To' send2-hook '~C problems@' 'set_header Reply-To: Bla blub <problems@...>' my_hdr and unmy_hdr buys me nothing because they're only executed on the next creation of a message but not actually applied to the current message. Is there a command which sets the header of the current message to this value? Otherwise it is time to write a patch. Thomas
