Sendmail timeout msg during draining input ??

[Peter Gillis]

Hi, hpux 11.11v1 model rp2470

I have been noticing some sendmail messages in the syslog. I am having problems trying to find out what they mean and what I should be doing about them. Can anyone assist here??
Plenty points.... message follows:

Apr 9 21:06:31 5C:saturn sendmail[2078]: l38K01E17049: timeout waiting for inpu
t from local during Draining Input

It's always a good idea to check sendmail.org for known bugs; yours is listed there:

timeout waiting for input from local during Draining Input

Make sure that the program does not generate output beyond a
status message (corresponding to the exit status). This may
require a wrapper around the actual program to redirect output
to /dev/null.

Such a problem has been reported for bulk_mailer.

Shalom Maria,

As I recall from the past some of your systems are exposed to the Internet.

From experience the message indicates that an inbound sendmail connection was initiated but time out before being complete.

This could indicate a malliciouis user or spammer is probing your system.
