一个客户试图发送一封较大的电子邮件,但是它被退回,并显示以下消息:
Hi. This is the qmail-send program at server2.hysir.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
<maria@laeknastodin.is>:
157.157.98.19 failed after I sent the message.
Remote host said: 552 5.3.4 Error: message file too big
我已经检查过了,我们这边没有对发件人邮件大小设置限制,而 157.157.98.19 这个 IP 地址是接收邮件服务器的地址。我可以假设 laeknastodin.is 的邮件服务器拒绝接收该邮件是因为它太大了,而不是我们的 SMTP 拒绝发送吗?
