Usage: %(program)s [options] [localhost:localport [remotehost:remoteport]] Options: --nosetuid -n This program generally tries to setuid `nobody', unless this flag is set. The setuid call will fail if this program is not run as root (in which case, use this flag). --version -V Print the version number and exit. --class classname -c classname Use `classname' as the concrete SMTP proxy class. Uses `PureProxy' by default. --debug -d Turn on debugging prints. --help -h Print this message and exit. Version: %(__version__)s If localhost is not given then `localhost' is used, and if localport is not given then 8025 is used. If remotehost is not given then `localhost' is used, and if remoteport is not given, then 25 is used. iNt SMTPServertDebuggingServert PureProxyt MailmanProxyisPython SMTP proxy version 0.2tDevnullcBseZdZdZRS(cCsdS(N((tselftmsg((s/usr/lib64/python2.7/smtpd.pytwriteXtcCsdS(N((R((s/usr/lib64/python2.7/smtpd.pytflushYR(t__name__t __module__RR (((s/usr/lib64/python2.7/smtpd.pyRWs s Rs, cCs;tjttIJ|r*tj|IJntj|dS(N(tsyststderrt__doc__tglobalstexit(tcodeR((s/usr/lib64/python2.7/smtpd.pytusagebst SMTPChannelcBseZdZdZdZdZdZdZdZdZ dZ d Z d Z d Z d Zd ZRS(iicCs tjj||||_||_||_g|_|j|_d|_ d|_ g|_ d|_ tj|_y|j|_Wn:tjk r}|j|dtjkrndSXtdIt|jIJ|jd|jtf|jddS(NiRsPeer:s 220 %s %ss (tasynchatt async_chatt__init__t_SMTPChannel__servert_SMTPChannel__connt_SMTPChannel__addrt_SMTPChannel__linetCOMMANDt_SMTPChannel__statet_SMTPChannel__greetingtNonet_SMTPChannel__mailfromt_SMTPChannel__rcpttost_SMTPChannel__datatsockettgetfqdnt_SMTPChannel__fqdnt getpeernamet_SMTPChannel__peerterrortcloseterrnotENOTCONNt DEBUGSTREAMtreprtpusht __version__tset_terminator(Rtservertconntaddrterr((s/usr/lib64/python2.7/smtpd.pyRms*          cCstjj||ddS(Ns (RRR-(RR((s/usr/lib64/python2.7/smtpd.pyR-scCs|jj|dS(N(Rtappend(Rtdata((s/usr/lib64/python2.7/smtpd.pytcollect_incoming_datasc Cstj|j}tdIt|IJg|_|j|jkr|sZ|jddSd}|j d}|dkr|j }d}n$|| j }||dj }t |d|d}|s|jd|dS||dS|j|j kr|jddSg}xN|jd D]=}|r\|dd kr\|j|dq,|j|q,Wtj||_|jj|j|j|j|j}g|_d|_|j|_|jd |s|jd n |j|dS( NsData:s500 Error: bad syntaxt iitsmtp_s'502 Error: command "%s" not implementeds451 Internal confusions t.s250 Ok(t EMPTYSTRINGtjoinRR+R,RRR-RtfindtuppertstriptgetattrtDATAtsplitR4tNEWLINER!Rtprocess_messageR&RR R/( RtlinetmethodtitcommandtargR5ttexttstatus((s/usr/lib64/python2.7/smtpd.pytfound_terminatorsP            cCsQ|s|jddS|jr0|jdn||_|jd|jdS(Ns501 Syntax: HELO hostnames503 Duplicate HELO/EHLOs250 %s(R-RR$(RRH((s/usr/lib64/python2.7/smtpd.pyt smtp_HELOs   cCs'|r|jdn |jddS(Ns501 Syntax: NOOPs250 Ok(R-(RRH((s/usr/lib64/python2.7/smtpd.pyt smtp_NOOPscCs|jd|jdS(Ns221 Bye(R-tclose_when_done(RRH((s/usr/lib64/python2.7/smtpd.pyt smtp_QUITs cCsd}t|}|| j|kr||j}|sAq|ddkr|ddkr|dkr|dd!}qn|S(Nits<>i(RtlenR=R>(RtkeywordRHtaddresstkeylen((s/usr/lib64/python2.7/smtpd.pyt __getaddrs ,cCstdI|IJ|r(|jd|nd}|sE|jddS|jr_|jddS||_tdI|jIJ|jddS(Ns ===> MAILsFROM:s501 Syntax: MAIL FROM:

It has been `de-transparencied' according to RFC 821, Section 4.5.2. In other words, a line containing a `.' followed by other text has had the leading dot removed.
