I configure a sendmail on my server (it has a dynamic domain name:

now, it can receive mail from outside and send mail from localhost to

but it cannot send outgoing email (e.g. from root@xxxxxxxxxxxxxx to
my_account@xxxxxxxxx)
The mail log says there is a makeconnection failure, as shown below. I
send a email from root@xxxxxxxxxxxxxx to xzfkiller@xxxxxxxxx:

It looks like your ISP is blocking connections to port TCP/25. Can you
try simply connecting with TELNET to gmail-smtp-in.l.google.com:25?
% telnet gmail-smtp-in.l.google.com 25
If that fails, then you can try connecting to the `submission' port,
which a lot of ISPs leave open:
% telnet gmail-smtp-in.l.google.com 587
If connecting to the submission port times out too, then you may have to
relay all your messages through the mail gateway of your ISP.
