We are using Exchange 2003 on Windows 2003 Server as backend mail server.
We have two SMTP Gateway Servers (Windows 2003) - both with reverse DNS
entries.
We have daily/periodic Event 4005 Warning ("The connection was dropped by
the remote host").
Sometimes we have this Warning to e.g. example.com, sometimes not ... ???
Is this normal SMTP behavior ?
Event Log entries from our primary SMTP Server:
