CentOS - Oct 2005 - Problems with Additional IP's, Sendmail, and iptables?

Hello CentOS,

Setup:
CentOS 4.1 (Latest YUM)
Sendmail
Multiple IP's on eth0:x (1 through 150 or so)
iptables

I've noticed that whenever I add another IP address to my servers on
one of the eth0:x aliases, the IP comes up fine and restarting
pure-ftpd and apache seems to be able to use the IP straight away.
Sendmail also 'seems' to use it fine, but something odd is occuring
that I have been able to track down.

When adding the IP, any domains pointing to the IP are added to the
local-host-names file, their email aliases are all configured, and
sendmail is restarted.  The problem is, none of the aliases ever work
unless I actually reboot the entire machine.

I've tried restarting as many of the running daemons as I can, I'm
either looking in the wrong places, or there's no other choice?  On
the old RedHat machines I had, this used to work fine without a
reboot.  Any suggestions?

This might be a stupid question but are you running newaliases after
modifying /etc/aliases?

If you restart Sendmail with either

service sendmail restart|reload|stop/start
/etc/rc.d/init.d/sendmail restart|reload|stop/start

the newaliases *should* be being run. But it certainly sounds like it
might not be.

Will.
