Basic email clients usually have little concept of an outbound queue. This can be a problem, for example when you send a mail to several people and mistype one name. With the default system configuration we will accept all the valid names but reject the invalid, but the mail client only knows to say “the send failed” (and often gives no clue as to why). This option results in us accepting any mail from your client software, without checking the names. Should we find any of them undeliverable we will later return you a notification mail, saying which names failed and in what fashion, and including a portion of your original mail for reference.
This option will only operate with clients configured to use Authenticated SMTP connections for sending mail.
