SENDMAIL Ages to start !!!!!

[Miguel Maria Godinho de Matos <Astinus@netcabo.pt>]

I am having some prblems with sendmail since the second time i booted linux.

I have linux for about 2 months now and i just now understood that my send 
mail deamon takes too long to start.

this is the log message that appeard when i upgraded linux red hat 7.1 to 7.2 
for the first time:

( firstboot after installing )

Nov 18 09:48:04 localhost sendmail[1031]: alias database /etc/aliases rebuilt 
by root
Nov 18 09:48:04 localhost sendmail[1031]: /etc/aliases: 42 aliases, longest

ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:00, mailer=loc

no problems this time, send mail started smoothly and quickly!!!!!!!!

Well, the first thing i did when i loged in was to configure my hostname and 
network devices.

So i changed my hostname to: AstinusGod, i added this host and it's network 
ip to the hostname table and so on!!!

since then look:

send mail takes ages to start and it keeps these kinda error messages in the 
log  files:

Dec  2 00:56:04 AstinusGod sendmail[9808]: My unqualified host name 
(AstinusGod) unknown; sleeping for retry
Dec  2 00:57:12 AstinusGod sendmail[9808]: unable to qualify my own domain 
name (AstinusGod) -- using short name
Dec  2 00:57:12 AstinusGod sendmail[9808]: fB20vCX09808: from=root, size=230, 
class=0, nrcpts=1, msgid=<200112020057.fB20vCX09808@AstinusGod>, 
relay=root@localhost
Dec  2 00:57:12 AstinusGod sendmail[9808]: fB20vCX09808: to=root, 
ctladdr=root (0/0), delay=00:00:00, xdelay=00:00:00, mailer=local, pri=30230, 
dsn=2.0.0, stat=Sent

I don't know what to do.... to solve this problem....

i figure that if i change my hostname to localhost again, and if i remove the 
ip entries i entered... it may be solved.. but i don't want that, just want 
sendmail to recognize them!!!!!

plz somebody help!!
