|
|
<p>今天老闆出國，發slack說手機不能寄信，看了一下，似乎是因為用GMAIL的APP來收信</p>
|
|
|
|
|
|
<p>然後google 不知道跟人家改了什麼，結果不接受原本的認證了… WTF ….</p>
|
|
|
|
|
|
<p>然後，這問題應該很久了，結果現在才在講 ….</p>
|
|
|
|
|
|
<p>底下都是用linux 主機來進行測試</p>
|
|
|
|
|
|
<p>windows環境應該也可以，只是要自己去安裝 openssl 軟體</p>
|
|
|
|
|
|
<p>To verify SSL, connect to any Linux server via SSH and use the instructions below:</p>
|
|
|
|
|
|
<p><strong>測試 SSL-IMAP 993 port</strong></p>
|
|
|
|
|
|
<pre><code>openssl s_client -showcerts -connect mail.example.com:993
|
|
|
</code></pre>
|
|
|
|
|
|
<p>結果應該會像是這樣</p>
|
|
|
|
|
|
<pre><code>2019-03-20 11:21:02 [changch@hqdc034 ~]$ openssl s_client -showcerts -connect mail.abc.com:993
|
|
|
CONNECTED(00000003)
