OK, the picture is clearer now, but still not entirely conclusive:

I suppose by "smpt" you mean "SMTP", which is "Simple Mail Transfer Protocol". This is a specialized protocol (based on the TCP protocol as a means of transport) to transport mails between a client and the MTA as well as between MTAs. (If you cannot make sense of the term MTA:
here is a short introduction).
If you maintain an Exchange Server (which is a software as close to a real MTA as Microsoft was able to program it) it perhaps uses SMTP transmissions to send and/or receive mails, both locally and to/from outside. Depending on the volume of data to send may or may not take several minutes to do so.
How about describing your environment and your problem a bit more completely so that we can provide concrete help instead of giving you some general information, hm?
I hope this helps.

net::smtp::server::relay
Server::Relay(3pm) User Contributed Perl Documentation Server::Relay(3pm)
NAME
Net::SMTP::Server::Relay - A simple relay module for Net::SMTP::Server.
SYNOPSIS
use Carp;
use Net::SMTP::Server;
use Net::SMTP::Server::Client;
use Net::SMTP::Server::Relay;
$server = new Net::SMTP::Server('localhost', 25) ||
croak("Unable to handle client connection: $!
");
while($conn = $server->accept()) {
# We can perform all sorts of checks here for spammers, ACLs,
# and other useful stuff to check on a connection.
# Handle the client's connection and spawn off a new parser.
# This can/should be a fork() or a new thread,
# but for simplicity...
my $client = new Net::SMTP::Server::Client($conn) ||
croak("Unable to handle client connection: $!
");
# Process the client. This command will block until
# the connecting client completes the SMTP transaction.
$client->process || next;
# In this simple server, we're just relaying everything
# to a server. If a real server were implemented, you
# could save email to a file, or perform various other
# actions on it here.
my $relay = new Net::SMTP::Server::Relay($client->{FROM},
$client->{TO},
$client->{MSG});
}
DESCRIPTION
The Net::SMTP::Server::Relay module implements simple SMTP relaying for use with the Net::SMTP::Server module. All this module does is to
take a given message and iterate through the list of recipients, doing DNS lookups for the associated MX record and delivering the
messages. This module makes extensive use of the plethora of other modules already implemented for Perl (specifically the DNS and
Net::SMTP modules in this case), and should give but a glimpse of the potential for extending the Net::SMTP::Server's functionality to
provide a full-featured SMTP server, native to Perl.
The above example illustrates the use of the Net::SMTP::Server::Relay modules -- you simply have to instantiate the module, passing along
the sender, recipients, and message. More formally:
$relay = new Net::SMTP::Server::Relay($from, @to, $msg);
Where $from is the sender, @to is an array containing the list of recipients, and $msg is the message to relay.
