Hello,

  I have a simple form that sends an attachment and some text information in the body of the message.  If I send the email without the attachment it works fine.  But if I try to send the attachment (It's about 3.5 meg)  It throws an error:

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, String ReplyTo, MailPriority Priority, String Subject, Mailformat Bodyformat, Encoding BodyEncoding, String Body, String[] Attachment, String SMTPServer, String SMTPAuthentication, String SMTPUsername, String SMTPPassword, Boolean SMTPEnableSSL)

  Anyone know how I can fix this from happening?  I did some cursory searches but couldn't find information about increasing the time out or how to troubleshoot this further.  Any help would be greatly appreciated.

Thank You

Kevin J Baird

Thanks Michael, but the problem isn't the upload timing out, it's the SMTP send portion.  That is what is timing out.  See the error above.  Normally I'd send it async but DNN doesn't seem to have this feature, so it times out the webpage.  Any ideas how to get around this problem?

Thanks

Kevin

3.5 Megabytes is a very large attachment, you should really be sending attachments below 1Mb in size.... (use ZIP compression).

Should you still wish to do it...well...

If you are able to send mails with very small attachments (say 1kb) then you should be looking at the email server and increasing the SMTP timeout there. Then again the email server could be actively configured to reject emails over a certain size.

If you don't own your email server try contacting your mail server postmaster and ask what their policy is.
