  Penet remailer
The Penet remailer was a pseudonymous remailer operated by Johan Helsingius[?] of Finland from 1993 to 1996.
Helsingius refused all requests to reveal the identities of the users of his remailer, until Scientology used the legal system to force him to reveal the identity of one person who had posted a Scientology document to the newsgroup alt.religion.scientology in January of 1995.
Helsingius successfully defended his remailer in court against Scientology's further attempts to obtain the identities of its users, but he felt that the legal system in his native country was not able to provide adequate protection against further legal attacks.

 Pseudonymous remailer
A pseudonymous remailer, as opposed to an anonymous remailer, is an Internet software program designed to allow people to write anonymous messages on Usenet newsgroups and send anonymous email under a pseudonym.
Primoridal pseudonymous remailers once recorded enough information to trace the identity of the real user, making it is possible for someone to obtain the identity the real user through legal or illegal means.
The most popular pseudonymous remailer was the Penet remailer, which lasted from 1993 to 1996.

  Anonymous remailer - Wikipedia, the free encyclopedia
There are Cypherpunk anonymous remailers, Mixmaster anonymous remailers, and nym servers, among others which differ in how they work, in the policies they adopt, and in the type of attack on anonymity of email they can (are intended to) resist.
Some remailers forward their anonymized email to still other remailers, and only after several such hops is the email actually delivered to the intended address.
Pseudonymous remailers, also called type IV A Pseudonymous remailer, simply takes away the email address of the sender, gives a pseudonym to the sender and sends the message to the intended recipient (who can be answered via that remailer).

 Penet remailer - Wikipedia, the free encyclopedia
Helsingius refused all requests to reveal the identities of the users of his remailer, until the Church of Scientology used the legal system to force him to reveal the identity of one person who had posted a Scientology document to the newsgroup alt.religion.scientology in January of 1995.
Because of the use of the legal system to attack the anonymity Penet offered to its users (and other attacks against anonymity elsewhere), more sophisticated anonymity networks were developed, like Type I Nymservers, of which not even the operator of the server can know the real identity of a pseudonym holder.
This is made possible by using cryptography and anonymous remailers such as cypherpunk remailers and Mixmaster.

 Life After Penet
Remailers are remote mail drops that "anonymize" e-mail and other Internet postings by removing the sender's address from a message and then sending it on, making it possible for whistle-blowers, dissidents, and others requiring anonymity to avoid revealing their true identities.

Some remailers change both types of address in messages they forward, and the list of forwarding nodes in email as well, as the message passes through; in effect, they substitute 'fake source addresses' for the originals.
More recent remailers use cryptography in an attempt to provide more or less the same service, but without so much risk of loss of user confidentiality.
Random padding of messages, random delays before forwarding, and encryption of forwarding information between forwarding remailers, increases the degree of difficulty for attackers still further as message size and timing can be largely eliminated as a traffic analysis clue, and lack of easily readable forwarding information makes ineffective simple automated traffic analysis algorithms.

Despite its relatively weak security, the Penet remailer was a hugely popular remailer owing to its ease of anonymous account set-up and use compared to more secure but less user-friendly remailers, and had over 700,000 registered users at the time of its shutdown in September 1996.
