[Mailman-Users] What happens when public_suffix_list.dat can't be loaded?

for the moment we are stuck with a buggy version of Python 2.7 that has 
recently become unable to load the URL


Since the end of April the attempt results in this error message:

Unable to retrieve data from 
https://publicsuffix.org/list/public_suffix_list.dat: <urlopen error [SSL: 
SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure (_ssl.c:661)>

Apparently this is caused by the lack of support for SNI in that Python 
version (python27-2.7.13-1.ius.el5)

AFAICT the list is only needed to map domain names to corresponding 
Organizational Domains in the context of DMARC handling. It looks to me as 
if that doesn't cause any problems, but I thought I'd ask ...

Thanks, Sebastian
