[Mailman-Users] UnicodeDecodeError during Archive Obscuring

[Jim Popovitch]

I've seen a increase in use of Unicod'ed email address which fail
HyperArch email obscuring and thus cause the msg to be shunted and not
archived.  

Specifically the problem lies in the encoding (strangely the error says
"Decode") of the text ' at ' (as a substitute for "@")  for Russian
users of GMail.

Here is the error in full:

This is a Mailman 2.1.9 system.

I did search the archives quite extensively, but I didn't find any cases
where Mailman was having trouble encoding the hard coded ' at ' into
unicode.  

Here is a sample (modified from original to protect the innocent) of the
message "From:" line:
     "=?ISO-8859-5?B?pyvY7zB08L6a0C==?=" <abc.xyz at gmail.com>

Any ideas on what to try/test/do?

Thanks!
