I can't identify the cause of impossibility to relay emails

my
Postifix mail gateway, from a Outlook express client.
Indeed, I get the problem while sending email with attachment with
size
above 5-6 MB..
From mail log, I saw:
postfix/smtpd[16988]: connect from unknown[xxx.yyy.www.zzz]
postfix/smtpd[16988]: 7B98D75008D: client=unknown[xxx.yyy.www.zzz]
postfix/cleanup[22797]: 7B98D75008D:
message-id=<[EMAIL PROTECTED]>
From client side I get a pop-up window that points out problems
with
server communication or even network..
What it couuld be inferred from postfix log above? How could
continue
to
investigate to get the cause of interruption?
Look for the records at the END of the SMTP session.
$ egrep 'postfix/cleanup\[22797\]|postfix/smtpd\[16988\]'

Thanks Wietse:

unknown[xxx.yyy.www.zzz]
Oct 29 10:34:25 av3 postfix/smtpd[16988]: disconnect from
unknown[xxx.yyy.www.zzz]
What I can suspect about the cause? Firewall, Protection software on
sending client or what?

It might be helpful to verify that postfix's debug_peer_level is still
set at 2 (default, I believe), then add the problem remote addresses or
domains to the debug peer list. Postfix will issue very detailed
messages isf you ask it to.
#debug_peer_list = 127.0.0.1
#debug_peer_list = some.domain
