It was just a tip about news groups. I remember when I started
with Linux that news and mailing lists confused me. That's why
I thought it would be useful for you.
More off-topic advices:
I understand your whole confusion; in general terms you should
Take It Easy. There are a lot of concepts you need to learn to
understand how things work (searching first in other sources
instead of "directly" asking here). Get used to the idea that
you will need to *teach* your ISP how to do things. Be sure
your ISP uses a friendly graphical interface that do the job
"out of the box", he has no idea about mail servers, ports,
encryption and network setup. To answer your question or to
solve an issue he must pay to someone that really knows about
the matter; obviously he won't.
And, don't waste your time changing to another company (or
country), you will experience the same all around the world.
DHCP (other thing you've asked in another thread) is another
example. Your ISP set your *home* LAN using dhcp just to not
hear about you each time you buy a new mobile device.
I should take "off-topic" by alias instead of eloi
PD: (¿Te acordás del Rasti? Tenés que ir con paciencia,
armando pieza por pieza.)
