Fetchmail and DSL link

[Cristiano Paris]

Hi everyone,

I've setup a DSL link and I noticed the /etc/ppp/ip-up.d/fetchmail file. 
Since I use fetchmail to retrieve my emails from my different mailboxes, 
I like the idea to have it running in the background a s a deamon. 
Anyway I think that it should be running only after a proper external 
Internet connection has been setup. I opened that file and changed its 
content to:

if [ -x /etc/init.d/fetchmail -a ! -x /sbin/resolvconf ]; then
        /etc/init.d/fetchmail start
fi

Anyway this didn't work since I do have resolvconf installed.

So I want to know the rationale behind the "! -x /sbin/resolvconf" 
condition...

Thanks!

Cristiano
