There is actually an alternative which works very well. I mention it here because it is a dumbed down version of UE, but it has the advantage of being open to changes. I know that some of the other developers here are using it. It allows smtp with authentication to any mail server that you have an account on. As you may recall Ray, I was having issues with my ISP over authentication and this is the solution I found:
No easy interface like UE has.
Requires at least some knowledge of PHP coding.
Works with ANY email server anywhere you have an account.
Can be tweaked and customized if you know some PHP.
