postcat - show Postfix queue file contents
postcat [-bdehnoqv] [-c config_dir] [files...]
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. 
- -r
- Print records in file order, don't follow pointer records.
    This feature is available in Postfix 3.7 and later. 
- -s offset
- Skip to the specified queue file offset.
    This feature is available in Postfix 3.7 and later. 
- -v
- Enable verbose logging for debugging purposes. Multiple -v options
      make the software increasingly verbose.
Problems are reported to the standard error stream.
  - MAIL_CONFIG
- Directory with Postfix configuration files.
