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.

NAME

       tcp.h, tcp - definitions for the Internet Transmission Control Protocol (TCP)

SYNOPSIS

       #include <netinet/tcp.h>

DESCRIPTION

       The <netinet/tcp.h> header defines the following macro for use as a socket option at the IPPROTO_TCP level:

       TCP_NODELAY     Avoid coalescing of small segments.

       The macro is defined in the header. The implementation need not allow the value of the option to be set with setsockopt() or retrieved with
       getsockopt().
