Background:
We are moving from an exchagne server to google apps.  All is going well.

Previously all out severs pointed to the Exchange server for sending out mail for our notification messages (such as "Service xxx was restarted".      I have set up the SMTP server to now just send the mail to the receipent domain.  It is set up on my SQL server.   It works, but a couple of questons are nagging at me.

1) When sending mail to another domain, the other mail server may do a reverse lookup to insure that the sender is who they say they are.  But I am unclear how this will work now.
As an example, I send mail to xyz.com from my smtp server located locally at 12.12.12.12.  Our mydomainname.com  resolves to 55.55.45.45.    Will the SMTP mail be rejected?

2) What exactly is a smart host.  It was setup to point to our exchange sever which now is going away, I blanked it, and the smtp sends fine to the outside email server.  Should I set this to the google smtp.google.com server address now?

Thansk for any guidance on this .
