請問有人SMTPS Relay用hinet的msr.hinet.net有成功過嗎?
 

問一下這個問題...
今天在試...
沒有一次有成工作..
全部都是在握手階段失敗...

心中一堆問號...
真的能用嗎?...:confused:....

不使用TLS\SSL一下子就出去了....

鵝試了一下連msa或msr的25或587port再走TLS(STARTTLS)是Ok的,但是連465port的SMTPS(SSL/TLS)就不work了,可能是Hinet沒開SMTPS吧:ase:ase....

問題是

有必要用加密的方式來傳送E-mail嗎?? 就算Client to msr.hinet.net端傳送時交給Server這一段是加密
但 Server to Server端這一段不加密 , 有意義嗎 ?? :rolleyes:

再者 Client to Server 這一段進行加密後傳送, 會讓Server的Loading增加 , Client一多起來
Server恐怕會無法接更多的連線 , 甚至有可能會掛點 !!

所以 ISP不提供這種運作方式,應該顯而易見的吧??

Server間的SMTP很多也都走TLS了啊(MUA連上mail server時都支援TLS了:flash: ),有些要求比較嚴格的地方還不接受自簽憑證咧,再說Internet server瓶頸通常是IO或頻寬,卡在CPU上的機率其實很低就是了:ase:ase....
