502#信息是什么意思

jhonlone

刚才有用户发信到tapsl.com,被退回，退信信息如下：

Your message did not reach some or all of the intended recipients.

      Subject:

The following recipient(s) could not be reached:

      xxxx@tapsl.com

on 2007-9-7 15:29

           


Could not deliver the message in the time limit specified.  Please retry or contact your administrator.

偶telnet上去，是这么个信息：
220 ************************
helo tapsl.com
502 unimplemented (#5.5.1)
以前没碰见过，是不是被封了？？求教

换了个IP试了一下，结果如下：

220 ************************
ehlo
250-king.lcgindia.com
250-SIZE 26214400
250-XXXXXXXA
250-AUTH LOGIN PLAIN
250 8BITMIME
mail from:XXX@gmail.com
rcpt to:554 refused mailfrom because valid local sender address required

何解？求高人相助

As mentioned, you ISP has changed the rules of the game on e-mail that
it will accept. They're now validating the RFC2821 envelope Sender:
e-dress and it must conform to their settings. (You'll have to find out
from them just what that is.)

I'd look at the values in (from v4.12a): "Tools | Internet Options |
General [tab] | General Settings [grouping] | My internet e-mail address
is:" as well as ".. | Sending (SMTP) [tab] | Edit | General [tab] |
Optional or advanced settings for sending mail [grouping] | Use an
alternate e-mail address for the SMTP envelope"

The second option would allow you to place a specific value to please
the ISP gods. as always, YMMV (Your Menus May Vary) *grin*
看到上面一条解决方案，但不太理解，哪位高人出来讲解下？
