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...
"TCPIP" 4324 "2017-02-19 01:09:13.572" "TCPConnection - TLS/SSL handshake failed. Session Id: 1028, Remote IP: 168.95.4.150, Error code: 336031996, Message: unknown protocol"

"APPLICATION" 2356 "2017-02-19 01:09:13.635" "SMTPDeliverer - Message 65: Message delivery thread completed."

心中一堆問號...
真的能用嗎?.......

不使用TLS\SSL一下子就出去了....
