Unless really exceptional loss of connectivity exactly at the time the SMTPSocket contacts the server, all messages are queued automatically and the server itself will take care of resending if the recipient is unavailable.Īt one point, indeed, an atomic bomb may fall on the roof, but I am not sure I need to live in fear because of that.Īll depends what you need to do with the mail.
