What Is Raid 1 Typically Used For When addresses, rather than free-form debugging information, are returned, EXPN and VRFY MUST return only valid domain addresses that are usable in SMTP RCPT commands. Often this can occur when the message contains a line that is too long and as such cannot be read by the MailEnable SMTP service.

A conforming server MUST NOT offer non-"X"-prefixed keyword values that are not described in a registered extension.

Other acceptable error status codes are 551, 552, 553, 450, 451, 452, 503, 455, and 555 (see RFC 5321 for their definitions).
