setup postfix

I've used google mail for years, and just migrated to zoho yesterday with a domain i bought. I love it, great product, lots of features. One thing that i cant get working yet is postfix on my home Ubuntu 12.04 server. I had gmail set up on it, and it worked great. I use it to send me alerts from the server. I looked around the internet and didnt see any info on how to set it up with zoho. Below are the settings that i need:

SMTP Relay host (i tried smtp.zoho.com:465), but it didnt work.

and below are some errors i received via /var/log/mail.log (when trying to send out a email)

Dec 7 18:15:01 MERCURY1 postfix/smtp[13380]: CLIENT wrappermode (port smtps/465) is unimplemented

i wasnt sure about the certificates log entry, if i need to have certs compatible with zoho, as well as the correct smtp relay setting.

I was hoping there was a howto, or wiki article entry that shows how to set up postfix.

Thanks for your help, Joe
