Zoe and Newspipe

The special time has come and I decided to integrate Newspipe with ZOE.
Apparently, the package available from Newspipe's homepage
(http://newspipe.sourceforge.net) does not support SMTP authentication so I
started to dab my finger in Python, only to discover that I can't get through
with it. The passwords (which are 100% correct, I'm using them with msmtp and
mutt to pass my outgoing mail to ZOE) are not working and I'm getting this
error:

Ok... this is/was a bug in the python smtplib:

Patch #1075928: AUTH PLAIN in smtplib.

"smtplib can not log in to some server using command AUTH PLAIN, it  
sends
``user\0user\0pass'' to the server, but ``\0user\0pass'' has better
compatibility."

http://cvs.sourceforge.net/viewcvs.py/python/python/dist/src/Lib/ 
smtplib.py?rev=1.69&view=log

No kidding.

Your best bet is to update to a more recent version of python/smtplib.

Cheers,

R.

Raphael,

thanks for good research work -- I'll try it with patched smtplib !!!

BTW: accessing zoe via secure http wirks good, but occassionally I'm
experiencing the following: sometimes the links need to be clicked on twice

There seems to be a glitch in the smtplib.login() method... the above 
credentials decode in 'lukaszlukaszqazws194'... note that the user name 
is encoded twice.

Nothing wrong with your test, rather something odd going on with 
smtplib...

server = smtplib.SMTP( 'localhost', 10025 )
server.set_debuglevel(1)
server.login( 'user', 'password' )

... results in "dXNlcgB1c2VyAHBhc3N3b3Jk" being send. Which, after 
decoding, looks like "useruserpassword". Note that the user name is 
there twice. Bad karma.

I'm not familiar enough with python to offer much help here. Your best 
bet is to contact the author of Newspipe and/or ask the owner of 
smtplib for some explanations.

Cheers,
