## NAME
       postcat - show Postfix queue file contents

## SYNOPSIS
       **postcat** [**-bdehnoqv**] [**-c** _config_dir_] [_files_...]

## DESCRIPTION
       The  [**postcat**(1)](https://www.chedong.com/phpMan.php/man/postcat/1/markdown)  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  com‐
       mand line, the program reads from standard input.

       By  default,  [**postcat**(1)](https://www.chedong.com/phpMan.php/man/postcat/1/markdown)  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 -b
              line, and stops when the end of the message is reached.

              This feature is available in Postfix 2.7 and later.

              figuration directory.

              This feature is available in Postfix 2.7 and later.

### -h -h
