我收到 550-无法路由的地址 550 发件人验证失败（回复 RCPT TO 命令）错误。

有什么帮助吗？
答案1
您的收件人拒绝您发送的邮件，因为无法验证发件人的电子邮件地址是否真实。
Jul 26 22:47:03 mydomain postfix/smtp[15883]: 658DD400BC: to=<[email protected]>, relay=lx31.hoststar.hosting[168.119.43.209]:25, delay=0.51, delays=0.14/0.13/0.19/0.05, dsn=5.0.0, status=bounced (host lx31.blabla.hosting[168.119.43.209] said: 550-Verification failed for <[email protected]> 550-Unrouteable address 550 Sender verify failed (in reply to RCPT TO command))
要向该收件人发送电子邮件，请使用真实的电子邮件地址作为发件人。
