The best way is to use postfix for global sending.

I'm going to assume that you have ubuntu's default setup, which is very minimal.

You will need to edit /etc/postfix/main.cf and edit the relay host

$ sudo nano /etc/postfix/main.cf

find 'relayhost' and edit it...
relayhost = your.outgoing.mailserver.com

...and add the following lines:

smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

You then need to create /etc/postfix/sasl_passwd with the format;

your.outgoing.mailserver.com   username:password

and run:
$ sudo postmap hash:/etc/postfix/sasl_passwd
$ sudo postfix reload

Then, any local mail sent should end up relayed to the mail server you
specified, using the login and password.

Check the logs (/var/log/mail.info) to see if it is working.

Be warned, ANY mail sent will go out to your relay.

I have a .forward in my home directory, so that any system mail to
root (or my userid, and system accounts) gets sent to a proper email
box.
