Hi Anni,
I have removed the entry of hostname.lcl and hostname from localhost line.
Some users were unable to login remotely so a smart guy rebooted the machine, unfortunatley it could not determine the ip so they /etc/hosts entry in the localhost was commented out. Then a second reboot was done.
The problem was not due to /etc/hosts but a failed disk, however when the machine rebooted the the ip conflict issue surfaced.
Anyway, regarding the sendmail issue I have solved with an entry like this:
1.2.3.4 hostname hostname.lcl
I don't see the annoying messages anymore.
IF I just put in a dot after the hostname, sendmail doesn't deliver the mail and I get the error 5.5.0.
Thanks

arp(8c) arp(8c)
Name
arp - address resolution display and control
Syntax
arp -a [vmunix] [kmem]
arp [-d] hostname
arp -f filename
arp -s hostname ether_addr [temp] [pub] [trail]
Description
The program displays and modifies the Internet-to-Ethernet address translation tables used by the address resolution protocol
The hostname is the name of the host system for which information will be displayed or modified.
With no flags, the program displays the current ARP entry for hostname.
Options
-a Displays current Address Resolution Protocol (ARP) entries from the specified name list and core files (next arguments). If not spec-
ified, uses and respectively.
-d Deletes the entry for the host specified by name (next argument).
-f Reads information from the specified file (next argument) and modifies entries accordingly. Entries in the file should be of the fol-
lowing form, with argument meanings as given previously:
hostname ether_addr [ temp ] [ pub ] [ trail ]
-s Creates an ARP entry for the host called hostname with the Ethernet address ether_addr. The Ethernet address is given as six hexadec-
imal bytes separated by colons. The entry will be permanent unless the word temp is given in the command. If the word pub is given,
the entry will be published. That is, the system will act as an ARP server, responding to requests for hostname even though the host
address is not its own. The word trail indicates that trailer encapsulations may be sent to this host.
