Argument Out of Range Exception...

[Phil Haack]

I get an argument out of range exception when I try to call email.Send...

Stack trace below.  I am expecting an exception in this case as I don't have an smtp server on my localhost (I am using the value "localhost" for my SMTP server).  I was testing the failure case and I expected an SmtpException, not this.

[ArgumentOutOfRangeException: Index and length must refer to a location within the string.
Parameter name: length]
   System.String.Substring(Int32 startIndex, Int32 length) +226
   DotNetOpenMail.SmtpProxy.ReadSmtpResponse() +39
   DotNetOpenMail.SmtpProxy.Open() +216
   DotNetOpenMail.SmtpServer.Send(ISendableMessage emailMessage, EmailAddressCollection rcpttocollection, EmailAddress mailfrom) +122
   DotNetOpenMail.EmailMessage.Send(SmtpServer smtpserver) +82

Hi-

I had a look, and it seems like this could happen if the server returns an invalid or partial response.  I just compiled a Debug version which checks for this and throws MailException if it can't understand the response code from the server:

http://dotnetopenmail.sourceforge.net/tmp/DotNetOpenMail.dll

Would you mind giving this a try for me and sending me the stack trace (or posting it here)?

Thanks!

Hi,

Seems this thread has more or less gone silent, but I have also faced a similar problem. The code I'm using is as follows:

==========================================
SmtpServer newsmtp = new SmtpServer(ConfigurationSettings.AppSettings["smtp"]);

string user = ConfigurationSettings.AppSettings["smtp_user"];
string pass = ConfigurationSettings.AppSettings["smtp_pass"];

newsmtp.SmtpAuthToken=new DotNetOpenMail.SmtpAuth.SmtpAuthToken(user,pass);

emailMessage.Send(newsmtp);

==========================================

I used the debug version you posted above and the output is as follows:

==========================================

r "DotNetOpenMail.EmailMessage" threw an exception. ---> System.IO.FileNotFoundE

Hope you can decipher what the problem is. Some useful information:

- D:/mailapp/ is the directory where the application and dll reside
- This problem only surfaced after I had to implement smtpauthtoken. Previously, the server didn't requre authentication to send mail and the app worked fine.
- The server which runs the app has been upgraded to .NET v2.0.50727

Thanks in advance.

Hi-

Sorry, that old debug version is way out-of-date.  Can you download the current source version from sourceforge and compile it?  If not, I can probably make one available somewhere....

Thanks,
