srsdp - Online in the Cloud

PROGRAM:

NAME

srsd - daemon interface to Mail::SRS

SYNOPSIS

srsd --secretfile=/etc/srs_secret

DESCRIPTION

The srsd daemon listens on a socket for SRS address transformation requests. It transforms
the addresses and returns the new addresses on the socket.

It may be used from exim using ${readsocket ...}, from sendmail via a TCP socket in a
rule, and probably from other MTAs as well. See http://www.anarres.org/projects/srs/ for
examples.

Arguments take the form --name or --name=value.

ARGUMENTS

--separator
String, specified at most once. Defaults to $SRSSEP ("=").

Specify the initial separator for the SRS address. See Mail::SRS for details.

--secret
String, may be specified multiple times, at least one of --secret or --secretfile must be
specified.

Specify an SRS secret. The first specified secret is used for encoding. All secrets are
used for decoding.

--secretfile
String, specified at most once, at least one of --secret or --secretfile must be
specified.

A file to read for secrets. Secrets are specified once per line. The first specified
secret is used for encoding. Secrets are written one per line. Blank lines and lines
starting with a # are ignored. If --secret is not given, then the secret file must be
nonempty.

--secret will specify a primary secret and override --secretfile if both are specified.
However, secrets read from --secretfile will still be used for decoding if both are
specified.

--hashlength
Integer, may be specified at most once, defaults to 4.

Specify the number of base64 characters to use for the cryptographic authentication code.

--help
Print some basic help.
