Hi,
I am developing a C# application to send requests to mail server to check
email addresses validity. I use a TcpClient object to connect to it with the
Connect(String hostname, Int32 port) method.
When I use my application at home I don't have any problem to connect and
get responses but when I try at work, I get the SocketException number 10061
: "target machine actively refused it". I don't have any proxy, maybe a
firewall.
My question is to know if there is another way to connect the servers (same
problem with sockets) or if there are existing parameters of the TcpClient
object to connect thru a firewall...
Thanks
