linux – 无法向Verizon地址发送电子邮件.所有其他地址都很好

yAAAn@verizon…net
SMTP error from remote mail server after initial connection:
host relay.verizon.net [206.46.232.11]: 571 Email from
96.31.68.20 is currently blocked by Verizon Online’s anti-spam system. The
email sender or Email Service Provider
may
visithttp://www.verizon.net/whitelist
and request removal of the block.
110510

我的服务器没有任何异常的邮件活动,我检查了所有黑名单网站,并没有出现IP.

我在Verizon的网站上使用了在线白请求,我收到了这条消息：

After investigation,Verizon Online
Security has determined that e-mail
from your IP address will not be
allowed access to the Verizon Online
e-mail domain due to one or more of
the following reasons:

Your IP has been blocked because of
spam issues or because your ISP
indicates that it is dynamically
assigned

No Reverse Hostname associated with
your IP address.

据我所知,这是垃圾……或者我在错误的地方寻找？

我需要哪些其他信息才能诊断出来？

如果有必要,我很乐意做出改变,但我不知道下一步该去哪里.

救命！

编辑：可能值得注意的是,我已经在两个月内尝试了4次移除请求.每次都有相同的结果.
