जब मैं इस usdc2spam2.slingmedia.com पिंग यह मुझे बिना किसी समस्या के उत्तर देता है। मैं windows 7
का उपयोग कर रहा हूं कृपया इसे हल करने में मेरी सहायता करें।
पिंग एक सबूत नहीं है कि आप एक ईमेल भेज सकते हैं। 'Telnet usdc2spam2.slingmedia.com 9000' आज़माएं। या यदि आप (Win7) में 'टेलनेट' नहीं है, तो उदाहरण का उपयोग करें [पुट्टी] (http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) –
क्या होता है जब आप 'telnet usdc2spam2.slingmedia.com 9000' का प्रयास करते हैं? मुझे संदेह है कि आप 'mail.smtp.port' प्रॉपर्टी में गलत पोर्ट निर्दिष्ट कर रहे हैं। – beny23
