Occasionally, one of our instances of exim-2.12 running on Digital Unix
OSF1 V4.0 generates a number of
"421 ... lost input connection" immediately after generating that
banner. A look at the source says that this happens when it gets
an EOF straight away.
There is no common pattern among the clients that this comes from. Some
are MS-Exchange servers, some are old sendmail servers, some are MUAs
(simeon mail). Everything will be running along just fine for months,
and then exim will start picking on a handful of hosts for this treatment,
and will continue for days to behave this way to those particular hosts.
Stoping and starting the listening daemon solves the problem for the next
few months.
This very much looks like on OS problem, but I haven't seen this with
anything other than SMTP, so I'm starting my query here.

Relativism is the triumph of authority over truth, convention over justice.
