Well, because sendmail starts AFTER the network is up and
by then you know your IP address you could write a little
script that changes (sed and awk) the sendmail.mc
file and issues a "make" in /etc/mail, and when
sendmail starts it knows the smarthost.
Alternatively you can re-write the /etc/rc.d/init/sendmail
in a way that when starting you have
after
prog="sendmail"
but before
"start() {"
something like this:
cd /etc/mail
echo "1. mail1.domain1.com"
echo "2. mail1.domain2.com"
echo "3. mail1.domain3.com"
echo "4. mail1.domain4.com"
read -p "what smarthost do you want?" -n 1 key
if [[ $key = 1 ]]; then
echo "copying sendmail.mc file for smarthost 1
cp sendmail.mc.1 sendmail.mc
elif [[ $key = 2 ]]; then
echo "copying sendmail.mc file for smarthost 2
cp sendmail.mc.2 sendmail.mc
fi
make clean
make
newaliases
cd /etc/rc.d/init
sendmail.mc.X have to have different smarthosts of course.
done!
