  • TMnet blocks port 25

    December 4, 2007 by Michael Foo
  • Dear Valued Customers,

            Please be informed that TMNet has blocked outbound SMTP (Simple Mail Transfer Protocol) traffic on port 25, on all outgoing email from its dynamic IP addresses users since 3rd December 2007.

            With this implementation, TMNet dynamic IP addresses users can only send outgoing email through port 25 using TMnet’s mailserver ( & while users who have their own mailserver (eg will not be able to connect to the mailserver through port 25.

            As a result, KKHost.Net has opened SMTP on port 26, on all its servers. All clients are advised to use port 26 on all outgoing email. To configure Outlook Express/Windows Live to use port 26, kindly follow the steps below:

    1.      Open Outlook Express/Windows Live
    Click on Tools -> Accounts
    Double-click on your email account
    Click on the tab Advanced
    Change ‘Outgoing mail SMTP’ from port 25 to 26
    Click Apply, and then OK
    You may start sending email through port 26 now.

            We apologise for the short notice.


            Thank you very much for your attention and have a nice day!
