When writing/sending a mail it is under Windoze not necessary to be online.
And I've heard that when using the SMTP-setting you should be online when
using linux... correct me if I'm wrong...

Well, being a newbie, I'm not going to rewrite anything. So for me the right
choice is the setting SMTP instead of sendmail in Kmail... That's all I
wanted to know. I should start using sendmail when I want to become a ISP?
Or maybe when I'm gonna be connected to the internet by a cablemodem?

Well... there is something about sendmail... and something about email...
but being a newbie, to combine these things into 1 is difficult. In the
netherlands we have a saying 'hij heeft de bel horen luiden, maar weet niet
waar de klepel hangt' / "he has heard the bell clinging, but doesn't know
where the bell is" (kind of) and that's the stuff I'm struggling with. I've
heard /read things about sendmail. I've heard/read things about SMTP... The
trick is to combine them together... And I'm working on that...
When I look in the MAN-pages I hardly see any examples about how it could
be. I like examples. Examples I can adjust to my needs. Just a discription
how it should be working isn't enough for me, sorry.
And Keith... this is/was your thread. But you mentioned the option
sendmail/smtp in Kmail and I was confused about that also. Confused for
other reasons, but confused nevertheless ;-)
Greetings,
David.
