Which SMTP server should I use, when develop im my PC?
I currently use mercury,
just because it's come with XAMPP.
but mercury is too difficult for me.
because it has too much settings.
so I am seeking more easy to use
SMTP soft.
is there any easy SMTP soft there?
http://lamsonproject.org/ Lamson looks very encouraging. It's pretty clean python, brand spanking new, and really trendy. It is also in active and responsive development, which is an advantage over many of the dinosaurs in the SMTP area.
JAMES(Java Apache Mail Enterprise Server) was the one i used and it was not great like sendmail but did the job with simple settings. And from the same stable of Apache made me choose it.
I did a quick Google search, and it sounds like you want something that is easy to use out of the box which you could also use with the programming languages included in XAMPP. Give Free SMTP Server a try. It's free, small, and claims to be easy to use, with full documentation.
freesmtp is a decent basic choice. http://www.softstack.com/freesmtp.html
There's also a sendmail.exe which is a very basic system (not actually sendmail, though it accepts basic sendmail arguments.) I've used it for things like sending bugzilla notifications and it works with PHP apps. http://glob.com.au/sendmail/
Mercury mail is a more fully featured smtp server that's fairly simple to configure (though it takes some hunting through it's weird menus). It's the mailserver built by Pegasus, and while not exactly "modern" it's fairly robust. http://www.pmail.com/whatsnew/m32401.htm
I've also used Apache JAMES for Java projects. James itself is fairly lightweight, but the JVM is not. But if you're already running a servlet container.

Dumbster is a fake SMTP server (in Java) which dumps email to a file. http://quintanasoft.com/dumbster/
Rumbster is a Ruby equivalent http://github.com/sr/rumbster
