This can return either the From: header, the Sender: header or the envelope header (a.k.a. the unixfrom header). The first non-empty header value found is returned. However the search order is determined by the following: - If mm_cfg.USE_ENVELOPE_SENDER is true, then the search order is Sender:, From:, unixfrom - Otherwise, the search order is From:, Sender:, unixfrom The optional argument use_envelope, if given overrides the mm_cfg.USE_ENVELOPE_SENDER setting. It should be set to either 0 or 1 (don't use None since that indicates no-override). unixfrom should never be empty. The return address is always lowercased, unless preserve_case is true. This method differs from get_senders() in that it returns one and only one address, and uses a different search order. tsendertfromsus-asciiiitN(ssenderR4(R4ssender( RtUSE_ENVELOPE_SENDERR#RtonelineR t getaddressest IndexErrort get_unixfromtsplittlower( Rt use_envelopet preserve_caset senderfirstR*thtfieldvaltaddrstrealnametaddresstunixfrom((s#/usr/lib/mailman/Mailman/Message.pyt get_senderss4        c CsC|djo ti}ng}xÉ|D]Á}|djoN|iƒpd}y!|id|iƒdfƒWqètj oqèXq'|i|ƒ}|oJg}|D]}|ti |dƒq©~}|i t ii |ƒƒq'q'Wg} xJ|D]B} | d} | dj o| o| i ƒ} n| i| ƒqùW| S(sReturn a list of addresses representing the author of the email.
