SMTP Port 25 is Blocked. RRS feed

  • Question

  • I am not able to send email through WindowsMail software. Its saying SMTP port 25 is blocked. I have OneCare installed in my Vaio laptop. There is no other security program installed other than OneCare.  Please give me a solution to this problem. Thanks a lot.

  • OneCare does not block SMTP port 25. To confirm that it isn't the firewall, turn off the OneCare firewall and try mail again.
    I suspect that your issue is that your ISP is blocking SMTP port 25 for sending mail when not connected directly to their network.
