how about something like this for starters:

nawk -f peto.awk path2VarMailUser

peto.awk:
Code:
BEGIN {
  # make 'records' to be separated by blank/empty lines
  RS=FS=""

  # create a pattern where something starts either one of listed strings
  headers="(^From )|(^Message-ID:)|(^Date:)|(^From:)|(^To:)|(^Subject:)"
}

# If a record starts with 'From ' ...
/^From / {

   # print the record number
   printf("\n\n=== THIS is MAIL MESSAGE #%d ===\n\n", ++msg)

   # iterate through the fields of a given 'record' - every field is a LINE, 
   # because records are 'blank line' separated sequesnce of lines
   for(i=1; i<=NF; i++) {

     # if a record field (a line) matches a pattern 'headers' - print that field
     if ( $i ~ headers) print $i
   }
}

# print any OTHER 'record' - this is a shorthand for 'print $0'

FORWARD(5)						      BSD File Formats Manual							FORWARD(5)

NAME
forward -- mail forwarding instructions DESCRIPTION
The .forward file contains a list of mail addresses or programs that the user's mail should be redirected to. If the file is not present, then no mail forwarding will be done. Mail may also be forwarded as the standard input to a program by prefixing the line with the normal shell pipe symbol (|). If arguments are to be passed to the command, then the entire line should be enclosed in quotes. For security rea- sons, the .forward file must be owned by the user the mail is being sent to, or by root, and the user's shell must be listed in /etc/shells. For example, if a .forward file contained the following lines: nobody@FreeBSD.org "|/usr/bin/vacation nobody" Mail would be forwarded to <nobody@FreeBSD.org> and to the program /usr/bin/vacation with the single argument nobody. If a local user address is prefixed with a backslash character, mail is delivered directly to the user's mail spool file, bypassing further redirection. For example, if user chris had a .forward file containing the following lines: chris@otherhost chris One copy of mail would be forwarded to chris@otherhost and another copy would be retained as mail for local user chris.
