I have errors lost connection and timeout after data, from the same
mail server. How I can fix this errors?
Just do nothing. These are not your errors, and you likely don't want
most of the mail from these systems.

I have problem with the biggest mail provider in my country, so I need
to accept this mails.
Postfix was the verision 2.1.5 on debian sarge, I installed the
backport postfix ( 2.3.7) with the possibility of disabiling pipelining,
I changed the mtu to 1000, iIchecked all again and again and there is
still timeout after data from the same domain.
I have not Cisco routers.
What is happening?
What's happening is your system doesn't receive any TCP
packets from the biggest mail provider in your country for at
least $smtpd_timeout (default 300 seconds).
Pipelining, MTU, etc. are likely not involved with this.
If you've reduced the smtpd_timeout parameter below its
default of 300s, you should put it back to the default. You
can try increasing the smtpd_timeout to 600s, but this seldom
helps. Usually the client has gone away - you can wait
forever and they won't send anything else.

If you have a very slow or highly congested internet
connection, you might reduce the number of smtpd processes in
master.cf.
Other than that, you can't force them to send you packets.
The problem is with them.
You can post a packet capture of the session for analysis, but
likely it will only show that the client stops sending...
nothing you can do about that.
