Fixing sendmail take a long time to start

I notice that my database box[FC6+Oracle10.2] take along time to startup. Sendmail and sm-client very very slow to start[ about 5 minutes ]. There's something wrong in /etc/hosts file. 'newalises' command take long time to update and finish with error below.

[root@ora10g ~]# newaliases
WARNING: local host name (ora10g) is not qualified; see cf/README: WHO AM I?
/etc/aliases: 76 aliases, longest 10 bytes, 765 bytes total
[root@ora10g ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.1.55 ora10g
[root@ora10g ~]#

To fix this, custom hostname[ora10g] need to append to localhost line in /etc/hosts.
[root@ora10g ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost ora10g
192.168.1.55 ora10g
[root@ora10g ~]# newaliases
/etc/aliases: 76 aliases, longest 10 bytes, 765 bytes total
[root@ora10g ~]#

Great !
If you want a faster startup, additionally use fix address instead of DHCP.
In FreeBSD, edit /etc/rc.conf and change the line
ifconfig_if0="DHCP" for ifconfig_if0="inet 192.168.1.55 netmask 255.255.255.0"
just note that _if0 corresponds to your real interface, and can be _em0, _rl0 and so on. The address 192.168.1.55 corresponds to example given and can be whatever you want, with netmask compatible.
