Exim comunication problem

Hi,
I ha ve a problem with my Exim version 4.43, it act as a MX server
that deliver email to our internal
mail server.
Very often we receive the same mail many times (often neswletters).
checking on EXIM log i find this error for everyone of the email tha i
receive more time

2007-02-14 13:52:36 SMTP timeout while connected to 192.168.1.102
[192.168.1.102] after end of data (46606 bytes written): Connection
timed out
2007-02-14 13:52:36 info@mydomain.it R=static_route T=static_smtp
defer (110): Connection timed out: SMTP timeout while connected to
192.168.1.102 [192.168.1.102 after end of data (46606 bytes written)

Our internal mail server receive the email correctly and delivery it,
but Exim keep it in the retry queue and resend the email after the
retry time.

We have traced a mail session with the command
exim -d -M <messageID>

and the result is te following
