Firstly, this is meaningless. All SMTP connections will time out
quickly if no initial commands are received. If you really want to test
your machine's timeout, enter MAI FROM and RCPT TO and DATA, send at least
one line, then wait....
Yes there are complaints of people sending mail from the outside whose
delivery is either delayed or does not get through. This means there are
problems with inbound mail. An SMTP server that times out after 4
seconds of inactivity is not reasonable given the possibility of delays
in others mail systems and on the internet.
It is possible that the timeout is NOT in postfix. Please
post some logs shownig the actual 'timeout' error message.
