"Service not available, closing transmission channel. The server response was: Cannot connect to SMTP server 74.125.25.108 (74.125.25.108:25), NB connect error 1460"
ผมลอง 587 กับ 25 ขึ้นว่า "Service not available, closing transmission channel. The server response was: Cannot connect to SMTP server 74.125.129.108 (74.125.129.108:25), NB connect error 1460"
