收到

Untrusted TLS connection established

came back to me and mentioned the Pfiff server use TLS 1.2 encryption, while SSI`s server still use TLS 1.0 encryption and therefore reject the receipt of the mails.
He also mentioned TLS 1.0 is not conform with the EU laws ( 歐盟一般資料保護規範 ) and is therefore asking if we could update our security standard to TLS 1.2.

Pfiff security standard: TLS 1.2
SSI security standard: TLS 1.0
--> SSI server reject mail

 

這邊調整看看

 

 伺服器TLS傳輸 : 系統自動判斷
TLS加密層級
密碼(ciphers)等級
用戶端TLS傳輸 : 系統自動判斷
TLS加密層級
密碼(ciphers)等級

用戶端調高

影響到的應該是 Windows XP , Windows 7

 

伺服器端
