Torsten, would you mind letting us know both the python and the .deb 
version by running 

$ python2.7 --version

and

$ dpkg -l python2.7

At least in debian's python2.7_2.7.1-8, default_port is still an instance 
attribute instead of a class attribute. 

If the ubuntu situation is the same, the missing patch is 
smtplib_01_default_port.diff , and you could work-around the problem by 
explicitly calling s = smtplib.SMTP_SSL("relay-auth.rwth-aachen.de", 465).

The patch got in with:

summary:     Issue #11927: SMTP_SSL now uses port 465 by default as 
documented.  Patch by Kasun Herath.

The last hunk, which fixes LMTP is still missing.
