mail takes forever to send?

If you check your /var/log/mail.log you will probably find something like this: My unqualified host name (localhost) unknown; sleeping for retry. This is because sendmail requires "hostname" to be a fully qualified domain name.
update your "/etc/hosts" file: nano /etc/hosts
to look like this: 127.0.0.1 localhost.localdomain localhost yourhostname
