I am bound to windows for a little bit (hiss!) and I cant seem to send mail through my FBSD Postfix server. All of my othere BSD machines point outgoing mail to I do that and get and error in OE (big hiss!):

The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'milne@blackfoot.net'. Subject 'test', Account: '', Server: '', Protocol: SMTP, Server Response: '554 <milne@blackfoot.net>: Relay access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79

EWven if I have SSL set to yes, I get the same error. If in fact it is a relaying issue...than why can my other machines send mail? I must be overlooking something, I am sure.

Just to clarify, your Windows box is pointing directly to your Postfix box as the SMTP server?

Is your Windows box IP address in the allowable range that you specified in Postfix?

Check your settings in postfix on what subnets are allowed to send mail through it.

Yes, it is pointing directly at the Postfix box as the SMTP server.

Everything locally is 192.168.1.* so the answer to that would be yes.

I never have done anything with settings regarding Postfix......not even sure how...but I bet it is in main.cf

look at the my_networks line in your /etc/main.cf

modify it accrodingly and then postfix reload, and you're off!

Nope, not yet. Here is a snip from my Postfix log followed by postconf -n:

I added the ip address of my windows laptop by hand under my_networks and it works.
Now, is that a secure thing to do...?

It should be no problem. You are just specifically allowing your laptop.
As far as your laptop, what is the subnet mask you have set for it? I noticed you have for the mynetworks portion and im wondering if that if you are using a different subnet mask, if that is the problem...
