Sending Mails to other domains on the internet

[Raviprasad143]

Hi,

I have successfully setted up Iredmail mail server latest version in my office(LAN) .All the features are working as expected.I created multiple sub domains with multiple user accounts.All the users were able to send and receive the mail each other from all the virtual domains.

Now my question is how do i setup my iredmail server to send the mails to public domains on the internet like yahoo,gmail...etc? I have got an static ip in my office.Please guide me to achieve this...
Any help highly appreciated.
