sendmail && dhcp

[Matthias Apitz]

Hello,

I'm using 11-CUR on my FreeBSD netbook and while moving around, I use
different network connections/interfaces: wlan0, tun6, ... depending on
the location where I boot. 

sendmail is started the normal way via /etc/rc.conf; but always finds on
startup the /etc/resolv.conf file of the last location (which ocf is not
valid anymore); the DNS is updated when the interface cames up later and
IP is assigned via DHCP; 

What would be the best way to restart (or defer the start of sendmail)
until the correct DNS is in place? For the tun interface I'm using a
devd(8) hook, but I'm looking more for a general solution.

Thanks

	matthias

referéndum, no solamente tiene gracia sino da en el blanco.-
