Direct emails from one account to another

It will vary slightly for each e-mail provider but if you go to account settings you should find some options to set up e-mail forwarding.
For example with Gmail: go to 'Settings' and then 'Forwarding and POP/IMAP'
For example with Hotmail:click the drop down arrow next to your name, select 'Options' then 'Mail' then 'Email Forwarding'.
For example with Yahoo: Select 'Options' then 'Mail Options' then 'Pop Access & Forwarding'

For all of the above make sure you have first logged into your email account
