Error message displays when sending test email


Dear Colleagues,

Email on our GRA system has never worked from the beginning. After reading the post found at, we then reconfigured the email section of the Web.config file, and then tested the system using the “Test Email” feature. Unfortunately, the “Test Email” feature displays the following error message:

at System.Net.Mail.SmtpClient.Send(MailMessage message)
at GRA.Communications.EmailService.SendEmail(String fromAddress, String toAddress, String subject, String body) at System.Net.Mail.SmtpReplyReaderFactory.ProcessRead(Byte[] buffer, Int32 offset, Int32 read, Boolean readLine)
at System.Net.Mail.SmtpReplyReaderFactory.ReadLines(SmtpReplyReader caller, Boolean oneLine)
at System.Net.Mail.SmtpReplyReaderFactory.ReadLine(SmtpReplyReader caller)
at System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint)
at System.Net.Mail.SmtpClient.Send(MailMessage message)

Please help us fix/debug this problem.

Thank you,

@tubaclarinet Can you post some screenshots of what you’re seeing and your web.config file?


Sorry about the delay in getting back to you on this.

As Caris says seeing the mail configuration section of your Web.config would help - you can private message it to me if you don’t want to post it. To me this indicates that the software cannot connect to the mail server that is configured.
