Not knowing how much of your example is real, here's a generic attempt based on the structure shown.

Save as process.pl
Run as perl process.pl cpolikowsky.input

Code:
#!/usr/bin/perl
#
use strict;
use warnings;

my $ver;
my @keep;

while(<>) {
   my $current = $_;
   if(/^-+$/) {
       pop @keep;
       $current = "";
   }

   if($current !~ /^$/) {
       push @keep, $current;
   }
   elsif(@keep) {
       write_out(++$ver, @keep);
       @keep=();
   }
}
write_out(++$ver, @keep);

sub write_out {
    my ($n, @lines) = @_;

    open my $fw, '>', "file$n.txt" || die;
    for my $line (@lines) {
        print $fw $line;
    }
    close $fw;
}


Output:
Code:
for f in file*.txt; do echo "$f"; cat "$f"; echo; done
file1.txt
user@gmail.com

file2.txt
db1
db2
db3
db4

file3.txt
dbrole1
dbrole2
dbrole3
dbrole4
dbrole5

filebyproc.d

filebyproc.d(1m)						   USER COMMANDS						  filebyproc.d(1m)

NAME

       filebyproc.d - snoop opens by process name. Uses DTrace.

SYNOPSIS

       filebyproc.d

DESCRIPTION

       filebyproc.d  is  a DTrace OneLiner to print file pathnames as they are opened, including the name of the process calling the open.  A line
       will be printed regardless of whether the open is actually successful or not.

       This is useful to learn which files applications are attempting to open, such as config files, database files, log files, etc.

       Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       This prints new process name and pathnames until Ctrl-C is hit.
	      # filebyproc.d

FIELDS

       CPU    The CPU that recieved the event

       ID     A DTrace probe ID for the event

       FUNCTION:NAME
	      The DTrace probe name for the event

       remaining fields
	      The first is the name of the process, the second is the file pathname.

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       filebyproc.d will run forever until Ctrl-C is hit.
