[quote]原帖由 "biml2002"]用什么工具可以使用查出邮件服务器是否有匿名转发功能？[/quote 发表：
telnet目标服务器，手动用SMTP的命令发送邮件，下面是一些例子：
1) 不支持relay的情况
[yjs@localhost yjs]$ telnet mail.oldhand.org 25
Trying 202.106.124.167...
Connected to mail.oldhand.org.
Escape character is '^]'.
220 perfectcenter.net ESMTP
helo test
250 perfectcenter.net
mail from: foo
250 ok
rcpt to: abc@test.com
553 sorry, that domain isn't in my list of allowed rcpthosts(#5.7.1)
quit
221 perfectcenter.net
Connection closed by foreign host.
2) 支持relay的情况
[yjs@localhost yjs]$ telnet mail.cctv.com 25
Trying 203.93.29.2...
Connected to mail.cctv.com.
Escape character is '^]'.
220 mail.intranet.cctv.com ESMTP server (Netscape Messaging Server - Version 3.6) ready Wed, 26 Feb 2003 00:38:15 +0800
helo test
250 mail.intranet.cctv.com

250 Sender <foo>; Ok
rcpt to: yjs@oldhand.org
250 Recipient <yjs@oldhand.org>; Ok
