我正在使用phpmailer做可能在网站上发送电子邮件，使用SMTP身份validation。 不过最近我发现我给了我一个错误，
SMTP Error: The following recipients failed: [email protected] 然后，我把debuggingvariables为真，在邮件类，我有以下的输出基本上说，它的临时问题，然后再试一次，我可以知道我该怎么做才能解决这个问题？
SMTP -> get_lines(): $data was "" SMTP -> get_lines(): $str is "220-servername ESMTP Exim 4.77 #2 Wed, 25 Jul 2012 08:59:03 +0530 " SMTP -> FROM SERVER:220-servername ESMTP Exim 4.77 #2 Wed, 25 Jul 2012 08:59:03 +0530 220-We do not authorize the use of this system to transport unsolicited, 220 and/or bulk e-mail.

你应该真的重试发送电子邮件，如果它说暂时的问题，以后再试。
此外，你可以看看你的邮件服务器，也许你可以确定为什么服务器发送这个错误信息。 （这是一个服务器错误信息）
我做了一个幸运的猜测，我认为你的/ var文件系统（或者你的邮件队列存储在哪里）是满的。 尝试发出df -h ，看看你是否有完整的文件系统。
诸如sendmail，postfix和exim之类的SMTP服务器软件被devise为处理大量邮件，在出现临时问题等情况下再次尝试。您的脚本不是，也不应该足够聪明来pipe理所有错综复杂的SMTP 。
如果是您的服务器，那么您需要查看它生成的服务器日志，以了解拒绝邮件的原因。 如果您使用的是第三方服务器，则需要联系第三方，以了解邮件服务器正在进行的操作。
