Hi,

Great library. This has been working for some time in PROD without any issues however I've just started getting this error. Has anyone come across this before?

System.Net.Mail.SmtpException: Mailbox unavailable. The server response was: If MAIL FROM is local then you must authenticate at System.Net.Mail.MailCommand.CheckResponse(SmtpStatusCode statusCode, String response) at System.Net.Mail.MailCommand.Send(SmtpConnection conn, Byte[] command, MailAddress from, Boolean allowUnicode) at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, Boolean allowUnicode, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at Postal.EmailService.Send(Email email) at System.Dynamic.UpdateDelegates.UpdateAndExecuteVoid2[T0,T1](CallSite site, T0 arg0, T1 arg1)

ok, fixed it, looks like my mail server settings changed. I had to authenticate using username/password and create an smtp client.
