[3.0/LINQ] SMTP fails someof the time
Okay i got a weird one for you
we have a open smtp server here in the building for sending out alerts and whatnot
I can send from my machine and get an email
My cube mate can send from his machine and i get the email ( they are currently all addressed to me)
If i log on to a machine in my computer lab it doenst work for me
If i other people from my same group ( that have the same AD permissions) with the exception of the one guy they get an error
Code:
System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine 10.209.xx.xx:xx
Here is the code i am using
C# Code:
private static void UsatSendMail(string[] To, string From, string Subject, string Message)
{
SmtpClient server = new SmtpClient("usat-xxxxx");
server.Credentials = new NetworkCredential("user", "pass");
MailMessage email = new MailMessage();
email.From = new MailAddress(From);
foreach (string T in To)
{
email.To.Add(T);
}
email.Subject = Subject;
email.Body = Message;
try
{
server.Send(email);
MessageBox.Show("Page Sent");
}
catch (SmtpFailedRecipientException error)
{
MessageBox.Show("error: " + error.Message + "\nFailing recipient: " + error.FailedRecipient);
//LogFile();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
//LogFile();
}
Ive also tried making it a clickonce install package to insure the other people have all the nesscary pre reqs ( .net3.5)
I'm really at a loss as to why it works in some situations and not in others.
If anyone has any idea on what i could look for that might explian this That would be really helpful.

Resolved
It was Mcafee virus
Some people in the company have the new version which blocks smtp and I have an older version.
