#7 Code hangs because of no timeout on sending commands

[Anonymous]

In SmtpProxy.Open(), besides this.ReceiveTimeout also this.SendTimeout must be set.

Otherwise there is no timeout when sending data TO the SMTP server

I believe this is resolved by moving the LoopTimeout declaration outside of the do/while loop in the SmtpProxy.ReadResponse() method.

Original code:

...
int count = 0;
// read until last response has been received
// (indicated by whitespace after the numerical response code)

do
{
int LoopTimeout = 0;
if (stream.DataAvailable)
{
count = stream.Read(serverbuff, 0, serverbuff.Length);
response = String.Concat(response, enc.GetString(serverbuff, 0, count));
}
...
============================================

Modified code:

...
int count = 0;
int LoopTimeout = 0;
// read until last response has been received
// (indicated by whitespace after the numerical response code)

do
{
if (stream.DataAvailable)
{
count = stream.Read(serverbuff, 0, serverbuff.Length);
response = String.Concat(response, enc.GetString(serverbuff, 0, count));
}
...

Solution proposed by Nobody is correct, but also the other change must be done
(In SmtpProxy.Open(), besides this.ReceiveTimeout also this.SendTimeout must be set.)
