Hi I am new to Exchange and I want to allow outgoing mail in my domain.

I can create a send connector, but I need to specify a SMART HOST/External SMTP server address. Which I dont have.

I assume a SMTP server will relay the messages to other SMTP servers around the world.

What SMTP servers can I use? Are there any free ones?

I really need help on sending outbound mail.

"Need"? How can you 'need' when you don't have one?
Is your firewall/gateway (whatever) on a fixed IP? If it is then you don't need the smarthost. If you are on a dynamic IP from your ISP then you need to call your ISP to get their SMTP relay address (either IP or host name, doesn't matter)

I,m on AOL and have a dynamic address.

What does the SMTP relay do then?

Why wouldnt I need a SMTP relay if I had a static IP?

Is SMART HOST the same as a SMTP relay?

Thanks

Yes, a smarthost is the same as an SMTP relay. If you're on AOL what are you doing running an Exchange server?
Anyway, you will have email settings from AOL that tell you what your POP3 configuration is. There will be one, like "pop.aol.com" and another like "smtp.aol.com" (whatever, I don't care) that you will have already. You use the latter in the box.
Why?
Because you're on a dynamic address you will have a lot of recipients who will reject your messages because they could be spam. The only solution is for you to route through something fixed, known and valid. That's what the relay is for.
