Queued up 274, 100 were sent, the rest gave this error:
System.Net.Mail.SmtpException: Failure sending mail. ---> System.IO.IOException: Unable to read data from the transport connection: net_io_connectionclosed. 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) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at Nop.Services.Messages.EmailSender.SendEmail(EmailAccount emailAccount, String subject, String body, MailAddress from, MailAddress to, IEnumerable`1 bcc, IEnumerable`1 cc) in f:\Own\NopCommerce\Sources\src\Libraries\Nop.Services\Messages\EmailSender.cs:line 78 at Nop.Services.Messages.QueuedMessagesSendTask.Execute() in f:\Own\NopCommerce\Sources\src\Libraries\Nop.Services\Messages\QueuedMessagesSendTask.cs:line 36
I've checked to see if the sending account is throttled at all, and it's not, it is set wide open.
Any ideas?
