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.

mconnect
mconnect(1) User Commands mconnect(1)
NAME
mconnect - connect to SMTP mail server socket
SYNOPSIS
mconnect [-p port] [-r] [hostname]
DESCRIPTION
The mconnect utility opens a connection to the mail server on a given host, so that it can be tested independently of all other mail soft-
ware. If no host is given, the connection is made to the local host. Servers expect to speak the Simple Mail Transfer Protocol (SMTP) on
this connection. Exit by typing the quit command. Typing EOF sends an end of file to the server. An interrupt closes the connection immedi-
ately and exits.
OPTIONS
The following options are supported:
-p port Specify the port number instead of the default SMTP port (number 25) as the next argument.
-r "Raw" mode: disable the default line buffering and input handling. This produces an effect similar to telnet(1) to port
number 25.
OPERANDS
The following operand is supported:
hostname The name of a given host.
USAGE
The mconnect command is IPv6-enabled. See ip6(7P).
FILES
/etc/mail/sendmail.hf help file for SMTP commands
