I was wondering whether someone could give me a suggestion of what the below error means when sending an invoice by email?
System.FormatException: System.FormatException: Smtp server returned an invalid response.
** 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.GetConnection()**
** at System.Net.Mail.SmtpClient.Send(MailMessage message)**
I have recently changed my email settings to the following:
I have spoken with support where my email is hosted and they are unable to find any problems that would stop emails sending from Manager at their end.
I have tried selecting use SSL, unchecking SMTP server requires authentication without success and combination of the two.
Any advice or suggestions would be much appreciated.
