Sendmail Logs

[David While]

Usually caused by the sending MTA terminating the connection prematurely -
you sometimes see this when spammers connect to your machine but they are
blocked by RBLs or your access control list

This should probably go to a Sendmail list, so could someone recommend a
good sendmail list please.  But . . .

I keep getting the following in my logs:

Oct 24 09:47:14 yoda sendmail[26342]: NOQUEUE: [63.123.249.67] did not
issue MAIL/EXPN/VRFY/ETRN during connection to MTA
Oct 24 09:48:49 yoda sendmail[26380]: NOQUEUE:
1-1-242.customer.bct.cmailinc.com [130.94.244.242] did not issue
MAIL/EXPN/VRFY/ETRN during connection to MTA
Oct 24 09:56:35 yoda sendmail[26707]: NOQUEUE: [63.123.249.67] did not
issue MAIL/EXPN/VRFY/ETRN during connection to MTA

LogCheck 1.1.1 reports this as a possible security violation.  Should I
be concerned?
