[e-privacy] SMTP/POP anonimizzanti [Fwd: POP3/SMTP scripts]

[marcoc1 at dada.it]

In lista Mixminion e' stato postato questo messaggio
 che descrive un (almeno in apparenza) molto interessante
 software aggiuntivo di Mixminion, che, se ho capito bene,
 permetterebbe di generare un pop/smtp anonimizzante che
 puo' anche gestire certi tipi di messaggi pseudonimi.

C'e' qualcuno in lista interessato e che ha tempo di darci
 un occhiata? Lo si potrebbe anche testare su uno dei 
 remailer Mixminion del Progetto Winston Smith.

Ciao.   Marco

Dear all,

I have checked in the /etc directory of the mixminion distribution a set of 
python scripts that pretend to be an SMTP server that anonymises all outgoing 
mail, and a POP3 server that decodes all incoming mail. Right now the 
mixminion binary is invoked for all the mixminion function.

Another interesting feature is that it allows for a transparent use of single 
use reply blocks. When a message containing a SURB is received the SURB is put 
in a repository, and a fictional email address is included in the "from:" 
fields. When a user replies to the email (using the SMTP proxy) the fictional 
address is stripped out and the message is routed through mixminion using the 
SURB. The user never has to manipulate SURBs directly. In addition to that a 
SURB is automatically included in all outgoing anonymous messages (there are 
security issues with this, but let's see how it goes).

I was interested in your views on how you feel about this usage paradigm. I 
have tested it with Mozilla and thunderbird: they make it easy to create 
profiles using different servers so an "anonymous" profile is easy to create 
and use. It avoid the anonymity community the task of creating custom email 
clients, or specialized plug-ins. It also give us the opportunity to support 
more functionality such as nym servers in the future.

The scripts necessary for running the proxies are:
IMAPproxy.py  minionProxy.py  minionSMTP.py  mmUtils.py  pop3d.py
and
python minionProxy.py --help
provides some initial guidance.

Looking forward to your comments,

George
