NAME

gpg-remailer - forward re-encrypted/signed PGP/GPG encrypted/signed mail to a group

SYNOPSIS

gpg-remailer [OPTIONS]

DESCRIPTION

Gpg-remailer decrypts received PGP/GPG messages, verifies the received signature, and re-encrypts the e-mail for a well defined group of recipients. Gpg-remailer can also be configured so as to process clear-text e-mail.

Using gpg-remailer the list of members of a group of people who want to exchange encrypted and authenticated e-mails (and maybe also clear-text messages) can be maintained at one location, allowing the members of the group to specify just one e-mail address to send PGP/GPG signed and encrypted (or optionally clear-text) e-mail to.

Gpg-remailer reads incoming e-mail from its standard input stream.

If the incoming e-mail is clear-text, it resends the e-mail to one or more configurable e-mail addresses.

If the incoming e-mail is PGP/GPG encrypted (and optionally signed) it re-encrypts the received information for every member of a configurable group, and send the re-encrypted information to one or more configurable e-mail addresses.

By itself, gpg-remailer is not a mailing list. However, the configured recipient address could be, e.g., a mailing list address, for further distribution of the processed e-mail. Gpg-remailer is a remailer: it uses the message's data, but not its headers. Having received an e-mail it resends, rather than forwards, the received e-mail. The e-mail that is received via gpg-remailer therefore contains a completely new set of e-mail headers.

A configuration file as well as command line options can be used to fine-tune gpg-remailer's behavior.

RETURN VALUE

Gpg-remailer always returns 0 to the operating system to prevent unknown mailer error messages in the MTA's logs. However, when gpg-remailer ends prematurely an error message is written to the standard error stream.

In order to use gpg-remailer the following requirements must be met (all commands should be issued by the root user):
