Perfect Email Server

Hi
I just setup CWP successfully! and running my site.
Now i want to setup a perfect email server.
Right now i am with default email settings and i can only receive email but can't send. Even i can see  my sent emails in Mail Queue.
I want to setup my email in Apple mail.
It would be great if some one create a detailed post to make a perfect email server with great reception.
Where should be mention IMAP/SMTP ports with SSL and without SSL. And details about DKIM & SPF Manager.
If someone already created detailed post about perfect email server then please refer to that link.

Please suggest me best solution.
Thanks

all servers have the same port for pop3/imap/smtp as this are standard ports, you can use this to test your smtp score.

after dkim/spf setup from cwp all should be working fine
