Hi,

I have DNN 4.5.5 running on windows server 2003 and SQL server 2005. Since yesterday i am seeing lots of general exceptions which regarding SMTP and my new users are experiencing long wait periods before getting the registration confirmation screen (after clicking 'Register'). Same thing i am experiencing as admin while authorizing the users.

Following is the General exception as given in event viewer, appearing over and over:

UserAgent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.11) Gecko/20071127 Firefox/2.0.0.11
DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider
ExceptionGUID: d6ee5fcc-9e45-4555-93bd-1f6ebffe51a6
InnerException: The operation has timed out.
FileName:
FileLineNumber: 0
FileColumnNumber: 0
Method: System.Net.Mail.SmtpClient.Send
StackTrace:
Message: System.Net.Mail.SmtpException: The operation has timed out. at System.Net.Mail.SmtpClient.Send(MailMessage message) at DotNetNuke.Services.Mail.Mail.SendMail(String MailFrom, String MailTo, String Cc, String Bcc, MailPriority Priority, String Subject, MailFormat BodyFormat, Encoding BodyEncoding, String Body, String Attachment, String SMTPServer, String SMTPAuthentication, String SMTPUsername, String SMTPPassword, Boolean SMTPEnableSSL)

Please tell me whats the solution to this problem.

Thanks in advance,

Raghu.

Hi Sebastian,

You are right, the test email under SMTP settings is responding very slow (sometimes with 'operation timed out' and same exception as above). I am using smtp.gmail.com:587 as the smtp server. This has worked like a breeze since creation of portal, only yesterday it started throwing problems. I have no clue what went wrong.
