  Thanks Rob,

  Is this the only possible solution, because I doubt, I can do such configuration in my MTA.

Correctly configure the MTA to provide an appropriate error code - see
the section titled "Spam Filtering" in the fetchmail man page.

Any half decent MTA will support this - which one are you using?

I have added the antispam option, but it didn't help. Still fetchmail gives one of the errors:

  fetchmail: MDA error while fetching from us...@do...
fetchmail: Query status=6 (IOERR)

  or

  : SIGPIPE thrown from an MDA or a stream socket error
fetchmail: socket error while fetching from us...@do... and delivering
to SMTP host localhost
fetchmail: Query status=2 (SOCKET)

  Thanks,

Please go and re-read my original email in this thread.  You *MUST*
configure the MTA to provide an error code - simply dropping the
connection is the wrong behaviour.

If you want any more help you'll need to provide details of your MTA,
otherwise you're on your own.

Dear Rob,

  I'm using oracle email server. It returns errors such as : 5.6.0: NULs not allowed or 5.5.1: unrecognized command, before it drops the connection, but fetchmail doesn't catch the error codes.
  I've added the antispam option as:  antispam 560,551
  Is that correct.?

It should be providing other messages and codes - for example your
"5.5.1" should be accompanied by a 500 error.  See RFC 2821:

http://www.faqs.org/rfcs/rfc2821.html

If you can't get Oracle email server (which by the looks of things
Oracle don't develop any more) to behave correctly then you're out of
luck.  You either need to abandon trying to get fetchmail to work with
such a broken server, or move to a working one.
