Are you sure the application tries to authenticate with correct username and password? In most cases "535 5.7.3 Authentication unsuccessful" response means incorrect credentials.
Please try to vary username as follows:
- username (just username)
- username@domain.com (full e-mail)
- domain.com\username (domain\user)
Please also try to send a message from the same account on the same SMTP server using another e-mail client like MS Outlook (or Outlook Express). Is it able to authenticate on that SMTP server?
If the above doesn't help, please enable logging SMTP session into a file, reproduce the issue and provide us with the log file for examination. You can enable logging as follows:
[C# syntax]
Code:
Smtp mailer = new Smtp();
mailer.Log.Enabled = true;
mailer.Log.Filename = @"C:\log.txt"; |
|
|
[VB.NET syntax]
Code:
Dim mailer = New Smtp
mailer.Log.Enabled = True
mailer.Log.Filename = "C:\log.txt" |
|
|
Please make sure the application has permission to write into the specified location.
You can send us the log file via Request Support Form.
Best regards,
Andrew

JFYI ..our mail server does not take any username or password.....please have a look at the code below...
Actually, Development SMTP server requires Username & Password but Production server does not. Application is working fine in Development environment but we are facing problems in Production ( Where we are supplying username/passwords as blanks).
C# - Code Looking for UserName/Password
smtpMail.SmtpServers.Add(ConfigurationManager.AppSettings["MailServer"] .ToString(), ConfigurationManager.AppSettings["MailUserName"].ToString(), ConfigurationManager.AppSettings["MailPassword"].ToString());
Web.config - Entry - In Production Environment
<add key="MailUserName" value=""/>
<add key="MailPassword" value=""/>
<add key="MailServer" value="mailgate.nzpost.co.nz"/>
Thanks;
Anand

Please try to use this overload of SmtpServerCollection.Add method. It doesn't require credentials and doesn't perform SMTP authentication.
So, for production environment, the code would look like:
Code:
| smtpMail.SmtpServers.Add(ConfigurationManager.AppSettings["MailServer"].ToString()); |
