That IP (and the reverse dns) are like Kevin said, I have an ADSL
connection. I know that its not so good to have all a host in my house,
but its personal (cause Im pablo, heh).

Well, most of 'errors' were not all of my parte, were DNS problems,
cause I was also moving my DNS (to zoneedit.com) and the mail that I was
using to test my server (If I was receiving) was also in problems.
But after 6 hours my mail start working, and I could receive and send
mails, so it was just to 'wait' for the DNS changes, now I can send mail
from pablo@???, and receive mails with the users that I have in
my server.

I think was just time to wait for the MX changes :(.
However, yesterday I was mailing friends, and in othe of those mails, I
received a mail in just 5secs from Outblaze telling me that I CANT send
mails from a SMTP server that its running in a dsl connection. I asked
in IRC how can I solve this problem, so when my smtp server detects that
Im sending a mail to user@??? use another smtp server
(like yifan.net).
Thanks!
