我在多站点上设置了WP Mail SMTP插件,该电子邮件是从父站点成功发送的,但是,当尝试从子站点发送相同或另一电子邮件时,出现以下错误:
ErrorInfo: The following From address failed: info@example.com : MAIL FROM command failed,RNPI Access denied by login ip protect
,550,SMTP server error: MAIL FROM command failed Detail: RNPI Access denied by login ip protect
SMTP code: 550SMTP server error: MAIL FROM command failed Detail: RNPI Access denied by login ip protect
SMTP code: 550
有人可以建议我如何解决该问题吗?
答案 0 :(得分:0)
SMTP服务器正在使用白名单,而未列出子站点的IP,或者它正在使用黑名单,而子站点的IP是IS。我不知道出现此错误的任何其他原因。
