mail problem from my main box

I recently blew away Redhat to replace it with Mandrake 9 when I lost
the fonts or something for the redhat config programs. I find I still
cannot send mail from the main box, but the laptop (also mandrake 9) is
ok. I looked at syslog and find this interesting but I don't know what
it means. BTW, I reformatted the system areas but not /home when I
re-installed.

From the syslod on laptop:

The error I get when sending mail from main is (mozilla 1.3.1)
Sending of message failed.
An error occurred sending mail: Unable to connect to SMTP server %S. The
server ........

Now the %S should be the outgoing server right? Is this something that
got saved in my root or home and that's why the result is the same after
reloading?

Before I reload and reformat all, I'd like to hear from you if you have
had any similiar experience.

Thanks
