Setting the `SMTPDebug` property results in different amounts of output:

`0`: Disable debugging (you can also leave this out completely, 0 is the default).
`1`: Output messages sent by the client.
`2`: as 1, plus responses received from the server (this is probably the most useful setting for debugging).
`3`: as 2, plus more information about the initial connection.
`4`: as 3, plus even lower-level information, very verbose.

You don't need to use levels above 2 unless you're having trouble connecting at all - it will just make output more verbose and more difficult to read.
