我从使用CodeIgniter框架编码的PHP应用程序发送电子邮件时遇到问题。 我已经在Apache，PHP和MySQL的VMWare上全新安装了Ubuntu Server。 我得到的错误是下一个：
220 linux11.dns-servicios.com ESMTP hello: 250-linux11.dns-servicios.com Hello abckion.es [83.49.xy] 250-SIZE 31457280 250-PIPELINING 250-AUTH PLAIN LOGIN 250-STARTTLS 250 HELP from: 250 OK to: 550-Verification failed for 550-mensaje de error" 550 Sender verify failed The following SMTP error was encountered: 550-Verification failed for 550-mensaje de error" 550 Sender verify failed data: 503-All RCPT commands were rejected with this error: 503-Sender verify failed 503 Valid RCPT command must precede DATA The following SMTP error was encountered: 503-All RCPT commands were rejected with this error: 503-Sender verify failed 503 Valid RCPT command must precede DATA 500 unrecognized command The following SMTP error was encountered: 500 unrecognized command Unable to send email using PHP SMTP. Your server might not be configured to send mail using this method. 我能做什么？
先谢谢你！！！
错误是与代码，而不是服务器。
to: 550-Verification failed for 550-mensaje de error" 550 Sender verify failed
看起来你正在把'To'设置为'mensaje de error''，显然这不是一个电子邮件地址。
您可以使用google轻松解决这个问题。 错误显然是：
550 Sender verify failed
