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

影響到的應該是 Windows XP ， Windows 7
