PROGRAM:

NAME


postcat - show Postfix queue file contents

SYNOPSIS


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

DESCRIPTION


The postcat(1) 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(1) 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
