Thanks everyone who responded.

I finally found a web page which answered all my questions, and then
some. The url is:
http://www.spencerstirling.com/computergeek/email.html

All I had to do was follow exim4's config prompts. I just had to specify
my ISP's smtp mail server as the smarthost I wanted to use. Apparently
my ISP does not require authentication on smtp to act as a smarthost. So
that was also quite convenient.

Since Exim4 uses encryption by default, I suppose I am okay in that
respect too.

I needed to make no changes in Exim4's config  files. However, I did
need to make the changes to fix the From and Reply-To address for each
user (otherwise the sending domain would be localhost.localdomain)[].
But since I wanted only one user to use this email system (sending
emails to various users externally), it was not much of a problem. I
just put the right lines in .muttrc to fix it:
# Set your "From" information
set from="my@some-email.com"
set use_from=yes
set use_envelope_from=yes


For mails sent out via scripts, I installed heirloom-mailx and used its
-r flag to fix the from address, like so:
$> echo "mail body" | mail -r my@some-email.com -s "mail config with
exim4" toaddress@some-email.com



Regards.
