POSTCAT(1) General Commands Manual POSTCAT(1)

NAME

postcat – show Postfix queue file contents

SYNOPSIS

postcat [-bdehnoqv] [-c config_dir] [files…]

DESCRIPTION

The postcat command prints the contents of the named files in
human-readable form. The files are expected to be in Postfix queue file
format. If no files are specified on the command line, the program
reads from standard input.

By default, postcat shows the envelope and message content, as if
the options -beh were specified. To view message content only, specify
-bh (Postfix 2.7 and later).

Options:

-b Show body content. The -b option starts producing output at the
first non-header line, and stops when the end of the message is
reached.

This feature is available in Postfix 2.7 and later.

-c config_dir
The main.cf configuration file is in the named directory instead
of the default configuration directory.

-d Print the decimal type of each record.

-e Show message envelope content.

This feature is available in Postfix 2.7 and later.

-h Show message header content. The -h option produces output from
the beginning of the message up to, but not including, the first
non-header line.

This feature is available in Postfix 2.7 and later.

-o Print the queue file offset of each record.

-q Search the Postfix queue for the named files instead of taking
the names literally.

This feature is available in Postfix 2.0 and later.

-v Enable verbose logging for debugging purposes. Multiple -v
options make the software increasingly verbose.

DIAGNOSTICS
Problems are reported to the standard error stream.

ENVIRONMENT
MAIL_CONFIG
Directory with Postfix configuration files.
