Method 1

I think this is the famous SSL issue of System.Net.Mail

System.Net.Mail with SSL to authenticate against port 465

You should use some external library or wait until Microsoft include this features in a framework release

Method 2

Just Change:

smtp.Timeout = 20000;

To

smtp.Timeout = 2000000;
