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. tsendertfromtiiN(R3R4(R4R3( RtUSE_ENVELOPE_SENDERR#tjoint splitlinesR Rt getaddressest IndexErrort get_unixfromtsplittlower( Rt use_envelopet preserve_caset senderfirstR*thtfieldvaltaddrstrealnametaddresstunixfrom((s./export/web/mailman/mailman/Mailman/Message.pyt get_senderss2         c Cs2|dkrtj}ng}x½|D]µ}|dkr|jƒpFd}y!|jd|jƒdfƒWqÚtk r}qÚXq%|j|ƒ}|r%g|D]}dj|j ƒƒ^q}|j t j j |ƒƒq%q%Wg}xG|D]?} | d} | dk r| r| jƒ} n|j| ƒqëW|S(sReturn a list of addresses representing the author of the email.
