Resolving unable to send email using dynamic domain

For those who own or have plans to buy a domain name with a different domain registrar and have a separate hosting service with another hosting company, you may face a problem with sending outgoing email using the hosting service smtp mail server (which normally is mail.yourdomainname.com etc).

The usual error message would be:

"Sending of message failed.
The message could not be sent because connecting to SMTP server mail.yourdomainname.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your SMTP server is correct and try again, or else contact your network administrator."




It's already been known that all outgoing SMTP port 25 been blocked by Telekom Malaysia Berhad, Telekom Malaysia Berhad had further revised and announced on 26th December 2007 that effective 15th Jan 2008, only outgoing SMTP port 587 is allowed for all outgoing SMTP email activities.

With this implementation, Streamyx customers or anyone else who have their own mail server will not be able to send e-mails. As an alternative, TM has provided an open relay server for these customers or anyone else who uses dynamic IP addresses.

But this doesn't seems to help even if you have set to port 587, should you have a separate domain registrar from your hosting service.

To go around this issue, I'm using Mozilla Thunderbird as my standard email client. Try the settings below:

For incoming POP mail server, you can use back the one that is provided by your web host. In this case it would usually be mail.yourdomainname.com

All you need to change is your outgoing SMTP server. Fill in the setting as shown.

You may notice that in the outgoing port, I have set it to port 25. It will still work because the TMnut has block out all others from using this port and only allowing their SMTP proxy server to use this port.

Should you need to setup and configure for other email clients, please refer the links below:
