我今天第一次给某日本教授发了封邮件
他的邮箱是XXX@mobile.ee.
但我每次发,都发不出去。
邮箱提示说是:
Hi. This is the qmail-send program at yahoo.com.
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.

Giving up on 195.250.185.155.

请给为大侠指教~这是为什么?
对了~给我朋友发都发得过去,就给这位教授发会出现这种情况
