Anonymous Remailer

Source: Riot

E-mail address:

Subject:

Additional header (CC:,Bcc:,Newsgroup:..):

Message Text:

Number of random remailers:
1 2 3 4 -- Increase
privacy and latency, but decrease reliability.

Number of message copies:
1 2 3 4 5 -- Increase
reliability. Only one copy will be delivered.

Your message will be sent through the anonymous mixmaster remailer system. This means that nothing will be left in the headers of the message to identify where the message came from, it will be encrypted before it leaves this system and it will be remailed through several other mixmaster remailers before it gets to its destination. It usually takes half a day for the message to get to its recipient.
