Hi!
1) As you said some ISP require authentication to send mail using their
smarthosts. If thats your case, go to-> Exchange System Manager->
Connectors-> right-click SMTP Connector-> Properties-> Advanced tab->
Outbound Security-> Enter the stuff for your ISP.
2) Do not do that. This is the hostname that will appear on the Exchange's
"greeting"... it should match the FQDN of your server (preferably your MX
record). Although, this is much more important when you are using DNS than
when using a Smarthost.
3) What Andrew said. The article that I mentioned
(http://www.sbslinks.com/DNS_Smarthost.htm) has a section on that subject
titled "Smarthost for specific domains" which outlines the procedure. On a
personal note... I find that using a Smarthost for all domains is a far
better choice (in most cases).
