Well, I'm not sure. That would be nice if I knew how to do it. When I am
"net connected", like right now, no matter what email client program I
use, in either Linux or Winbroke, in order to send email I have to set
up SMTP AUTH in the mailer program. Right now I am using Sylpheed, and I
have to set up SMTP AUTH in it in order to send mail. Now, I understand
that sendmail/postfix/exim are double-duty programs that can be
configured as either clients or servers (is that right?). But I thought
a "server" was for receiving and forwarding emails, such as an isp does.
If there is a way to bypass the ISP when sending email, then I want to
know how to do it (with postfix). And, if that is true, then what is
SMTP AUTH for? I'm sure by all of my ranting here you all can tell that
I don't know much about the subject. Please, anyone, jump in here and
"straighten" me out! I really am trying to learn, but good documentation
on client side SMTP AUTH is, well I can't find any.
Thanks,
Jerry
