Or like this: 

use strict; 
use warnings;

my $line="19476 2013-04-05,12:10:51.909293 host:internal.machine44.com
+pany.net main INFO Running normally with ACTION=<processing> FAN_A=<O
+K> FAN_B=<OK> SEND=<Sent mail (221 2.0.0 Service closing transmission
+ channel)> FAILURE=<2>";

$line =~ s/\d+ (.*?) /DATE=<$1> /; # to give you the date as well ;)
my %info = $line =~ /(\w+)=<(.*?)>/g;

print "$_:$info{$_}\n" for keys %info;
