An entry like that would be generated if something on the local system connected to the MTA and then disconnected without issuing commands. This happens, for example, when you have a monitoring system checking the service by connecting to it, such as nagios. Regarding why it says localhost.localdomain, that's probably just a reflection of how you have 127.0.0.1 listed in /etc/hosts. > -----Original Message----- > From: redhat-list-bounces@xxxxxxxxxx > [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Bill Tangren > Sent: Thursday, July 19, 2007 9:34 AM > To: General Red Hat Linux discussion list > Subject: sendmail log entry > > I am running a restricted sendmail relay under RHEL ES 4. > Lately, I have been getting this in the logs: > > sendmail[9730]: l6J1H6Cg009730: localhost.localdomain > [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA > > I've seen this before for outside email addresses, but not > for localhost.
