It is to vague a question. You'd better read the docs, then ask precise questions, if you don't understand something.

i can telnet into smtp and relay mail asif it comes from any domain for example:
mail from: user@anydomain.com
I would like to stop this from happening.
How would i secure it.
Im not comming right with the docs.
Look through the docs for a parameter called $mydomains. I think that determines which domains are allowed to send email through your server. There is also a parameter called $mynetwork, I think.
Ummm... Postfix will not relay by default. If it is currently functioning as an open relay (which you can verify by going to www.abuse.net/relay.html) then you have a problem with your configuration. I would start with that. - herman
