I was lookingt at all the bunch of packages I installed in my newbieness frenzzy. So now I wonder who handles the internal emails. As in, mail notification to root.

I found I got installed procmail, fetchmail,mailx, and exim4.

I my memory doen't fail me, it was procmail by default at installation time?

Can I remove the others safely without breaking sumting ?

Or... how do I found out which is the one ? [/em Qucho looks arround for Neo]

Check your running processes..

I would think it is procmail, if so you should be able to remove anything that isn't being used without any problems.

I looked over the running processes. Exim4 was running.

So I got rid of 'fetchmail' since that one does not appear to be necesary since exim is working.

Regarding 'procmail'. I left it alone since I dont really understand what this program does and the documentation seems obscure to my noobiness, but feels like it does some 'behind the sceen' work.

And mailx description in apt-get says it is a important application and many programs use it even if I dont notice it. So I am leaving it too.

I guess this is one of those things not meant to be mess with by a noob like me.

But... some day... some day... I will see the light ! :P
