【問題】請教一個被gmail退信的原因?

Hi. This is the qmail-send program at localhost.localdomain.
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.

<[email protected]>:
209.85.199.27 failed after I sent the message.
Remote host said: 550-5.7.1 [122.116.138.57] The IP you're using to send mail is not authorized
550-5.7.1 to send email directly to our servers. Please use the SMTP
550-5.7.1 relay at your service provider instead. Learn more at
550 5.7.1 http://mail.google.com/support/bin/a...y?answer=10336 b8si3249123rvf.1

上述是我從我家的mail server寄出被退信的內容
看起來並非是受到黑名單的原因
也已經去跟hinet申請ip反解
但是仍然無法寄到gmail
請問有誰也碰過這種怪問題嗎?

gentoo ~ $ nslookup
> server 168.95.1.1
Default server: 168.95.1.1
Address: 168.95.1.1#53
> 122.116.138.57
Server: 168.95.1.1
Address: 168.95.1.1#53

57.138.116.122.in-addr.arpa name = gh1220.idv.tw.
57.138.116.122.in-addr.arpa name = dreamhome.idv.tw.
57.138.116.122.in-addr.arpa name = devadeco.com.
57.138.116.122.in-addr.arpa name = slive.com.tw.

會不會是 multi PTR 的關係?

對不起! 我不太了解
之前我是顯示反解出來是hinet之類的
後來我朋友的devadeco.com跟我的gh1220.idv.tw
都無法寄到gmail後
才去hinet申請多組反解
請問這個動作是否多餘的

你的 PTR 有四筆紀錄:
57.138.116.122.in-addr.arpa name = gh1220.idv.tw.
57.138.116.122.in-addr.arpa name = dreamhome.idv.tw.
57.138.116.122.in-addr.arpa name = devadeco.com.
57.138.116.122.in-addr.arpa name = slive.com.tw.

我猜是因為這樣才會被 gmail 退信吧

不過 qmail 有支援 smart host
直接指定你 ISP 提供的 SMTP Server 不是比較方便嗎?

謝謝您的回應
退信的問題是在設四組ptr之前
之前是指向hinet 也有單純指到gh1220 也是被退
後來是朋友反應他的devadeco也被退
才設上四組
qmail我還在摸索
因為我是裝plesk 它內建qmail
所以我還在摸索當中

'The IP you're using to send email is not authorized...'
In order to prevent spam, Gmail refuses mail when the sending IP address does not match the sending domain. To send mail from your server to Gmail, we suggest using the SMTP relay provided by your ISP. Please note that we are unable to whitelist IP addresses or otherwise make exceptions at this time.
