BSNL Blocked Port 25?

[arijitgupte]

I used BSNL connection and my office email server uses Port 25 as the outgoing port.For the past two days I have been unable to send emails, though I can receive emails. I did a telnet on port 25 got an error.I tried it at my friends place accross the city and got the same result.Does any one know if BSNL has blocked port 25?I had heard that many ISP's are blocking port 25 to prevent Spaming.Arijit

If you are using Windows 7, telnet is disabled. You will have to enable the feature in Windows 7

Yes. BSNL Pune is blocking port 25 to curb SPAM. However, BSNL is providing an alternate method to send emails. Kindly refer to http://maharashtra.bsnl.co.in/03112012_BSNL_User_Guide.pdf (This can be found in "Outlook Config Settings" on the left hand side menu in http://maharashtra.bsnl.co.in).

Using the above guide you can send emails even if port 25 is blocked.
