Postfix

[Fridtjof Busse <fridtjof.busse@gmx.de>]

Hi
I had a small problem with postfix, so I asked on the postfix-users-list 
and it looks like the problem is caused by a small bug in OpenBSD.
I'm not sure if that's correct, so I'm just forwarding Wietse's answer

This error is reported on some operating systems that destroy a socket
when the client closes the connection before the server accept()s it.

It's only a warning. I will remove it, because Postfix recovers
from such conditions just fine, and the paranoia serves no useful
purpose.

Different people re-invent the same problem all the time.  Old BSD
code had graceful close(), that is, data written successfully was
not thrown away when close() happened before accept().
