收到回信了…
Hello,
Thank you for writing to Yahoo! Mail.
We appreciate your report as your input helps us to identify ways to
constantly maintain and improve our service. We apologize for any
inconvenience this has caused you. If you notice any further
difficulties when delivering to Yahoo! Mail accounts, after waiting a
reasonable amount of time, please let us know by replying directly to
this email. However please note the following:
If you are receiving the error code “421 Message from x.x.x.x
temporarily deferred” or “451 Message temporarily deferred – 4.16.50” in
your SMTP logs, this indicates that the message you attempted to send
was not accepted by Yahoo! Mail servers. It is not a permanent error;
your system will automatically re-try later. If, after attempting to
deliver to Yahoo! and receive the 4.16.50 error repeatedly and conform
to the best sending practices outlined in the following page, we
encourage you to apply for prioritized sending at the link below.

If you are receiving a separate error than that above, please provide

一看就知道,又是在打官腔… :x
我把 ###.###.###.1 跟 ###.###.###.2 這兩個 IP 丟到 DNSBL 測試網站測試過,通通都是正常的。
而且,這兩台機器的網域都有 SPF 設定。
Yahoo 不使用開放架構,自行建置黑名單,回報後又沒給理由,著實令人頭疼。
我的研判,原因可能是「spammer 使用偽造的 Yahoo 信箱位址當作 From,丟信到 mail server,mail server 查不到收件人,嘗試退信,就回彈到 Yahoo 去」,所以在 mail server 上面改了些設定。
###.###.###.1 跟 ###.###.###.2 這兩個 IP 分別使用 Exim 跟 Postfix 作 MTA 。
我對 Exim 不熟,所以只調整了 Postfix 的 rule ,在 main.cf 用了這些設定(大部分是原本就有的):
#
bounce_queue_lifetime = 1h
maximal_queue_lifetime = 3d
#
smtpd_sasl_auth_enable = yes
smtpd_sasl_auth_clients = yes
broken_sasl_auth_clients = yes
smtpd_sasl_local_domain =
smtpd_sasl_security_options = noanonymous
#
smtpd_recipient_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
permit_mx_backup,
check_recipient_access regexp:/usr/local/etc/postfix/access_regex,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
reject_unauth_destination,
reject_unknown_reverse_client_hostname
#
smtpd_client_restrictions =
permit_sasl_authenticated,
permit_mynetworks,
check_client_access regexp:/usr/local/etc/postfix/access_regex,
reject_unknown_reverse_client_hostname,
reject_rbl_client bl.spamcop.net,
reject_rbl_client sbl.spamhaus.org,
reject_rbl_client list.dsbl.org,
reject_rbl_client cblless.anti-spam.org.cn,
permit
#
smtpd_sender_restrictions =
reject_non_fqdn_sender,
reject_unknown_sender_domain
在 /usr/local/etc/postfix/access_regex 這個檔案裡面則是塞了這些:
/dsl\./ REJECT
/\.dsl/ REJECT
/dynamic\./ REJECT
/\.dynamic/ REJECT
/-dynamic/ REJECT
/dynamic-/ REJECT
/\.dynamicIP\./ REJECT
/\.dyn/ REJECT
/dyn\./ REJECT
/dyn-/ REJECT
/-dyn/ REJECT
/dynpool/ REJECT
另外,建議有相同困擾的人,運用 Gmail 信箱當作 mail 溝通管道。
PHP 的系統可以考慮導入 libgmailer 。
有人跟我說,要人家放棄 Yahoo 的信箱很難,因為Y拍的店主都得用 Yahoo 的信箱。
可是… 露天+搜尋引擎關鍵字廣告不好用嗎? 而且,目前露天還不會向店長勒索!

Google Earth 的圖資更豐富啦~
剛剛,看到快速啟動裡面的 Google Earth 圖示,突然想到,它很久沒被我開出來玩了。
手邊的工作正好完成了一個段落,就開起來玩玩。
透過 Google Earth 的「檢查線上更新」功能,我把版本更新到 4.2.0205.5730 。
這個版本不僅提供了星象圖(Google 稱之為 天際功能),圖資也變得更豐富啦!
而且,除了台灣道路名稱的顯示之外,台灣的許多高樓建築也都有 3D 模型了。 (邪惡)
我順手擷取了幾張圖出來:
當然,雪梨歌劇院、埃及金字塔、凱旋門、艾菲爾鐵塔、…,也都有 3D 模型。
比較可惜的是,我找不到台北的美麗華摩天輪跟高雄夢時代的 3D 模型…
除了以上的圖,比較奇特的圖應該是這張,高雄的小港機場南邊的衛星空照圖好像有個電磁力場。
(時空傳送門建造中? )
總之,從以前到現在,我一直覺得 Google Earth 是一套頗好玩的軟體,而且,它愈來愈有趣了。
Anyway, 有興趣的人可以自行 下載 Google Earth 來玩看看。
