[Mono-aspnet-list] Socket error sending secured mail.

I'm sorry but maybe I'm missing something. I used field specification 
to set the port so it's not 25

msg.Fields[" 
http://schemas.microsoft.com/cdo/configuration/smtpserverport"] = 465;

I looked at System.Web.Mail.SmtpClient source code and it reads those 
fields from message to set socket connection so it should work, if it 
uses port 25 it should give a timeout error, not an immediately 
socket exception I think.
Field specification works in MS.NET even if not using exchange server 
(The same code works against google in windows environment).
Maybe is one of the most items of MS.NET that does not match the 
aspected behavior but looking at Mono source code it should use those 
fields, unless there's some problem with TLS. I tried  your code on 
2.4.2.3 VM and it waits indefinitely, I've to restart apache. Maybe 
it's because I don't use Mono 2.6 but this version it's pretty new, 
in FAQ there's no version specified, I thought it could be used also 
with older versions, it's a problem for me to update.
